A 3D camera for safer autonomy and advanced biomedical imaging

Posted By Graphene Council, Thursday, February 6, 2020
Researchers at the University of Michigan have proven the viability of a 3D camera that can provide high quality three-dimensional imaging while determining how far away objects are from the lens. This information is critical for 3D biological imaging, robotics, and autonomous driving.

Instead of using opaque photodetectors traditionally used in cameras, the proposed camera uses a stack of transparent photodetectors made from graphene to simultaneously capture and focus in on objects that are different distances from the camera lens.

The system works because of the unique traits of graphene, which is only one atomic layer thick and absorbs only about 2.3% of the light. A pair of graphene layers can be used to construct a photodetector that can efficiently detect light, even though less than 5% of the light is absorbed. When placed on a transparent substrate, instead of a silicon chip for example, the detectors can be stacked, with each one in a different focal plane.

As described by Prof. Ted Norris: “When you have a camera, you have to have a focusing adjustment on your lens so that when you’re focusing on a particular object like a person’s face, the rays of light that are coming from that person’s face are focused onto that single plane on your detector chip. Items in front or behind the object are out of focus.

But if it were possible to stack different detector arrays each in different focal planes, then they could each image accurately a different place in the object space simultaneously. What’s more, if you can detect multiple focal planes of data all at the same time, you can use algorithms to reconstruct the object in three dimensions. That is called a light field image. We have demonstrated how to use transparent focal stacks to do light field image and image reconstruction.”

In addition to basic object identification, the current paper shows how their device can detect how far away something is – making it suitable for applications in autonomous driving and robotics. It is also ideal for biological imaging in cases where it is important to image three-dimensional volume.

For its ultimate success, the project required complementary expertise in three areas. Prof. Zhaohui Zhong’s team developed the graphene devices; Norris’ group worked on the design features of the optical instrument and demonstrated the devices in the lab; and Prof. Jeff Fessler’s group, which developed the image reconstruction algorithm.

Fessler echoed the other faculty in stating the group of nine researchers consisting of faculty, postdocs and students “coalesced as a great team, all learning from each other and contributing different aspects of the final paper.”

Inspiration for the camera came from previous research of Zhong and Norris on highly sensitive graphene photo detectors, published in Nature Nanotechnology in 2014.

The current transparent graphene sensors fabricated so far are too low-resolution to depict images, but the initial experiments showed that the lens focused light from a different distance on each of the two sensors. Work is continuing on the project.

New production method for carbon nanotubes gets green light

Posted By Graphene Council, Thursday, January 9, 2020
A new method of producing carbon nanotubes - tiny molecules with incredible physical properties used in touchscreen displays, 5G networks and flexible electronics - has been given the green light by researchers, meaning work in this crucial field can continue.

Single-walled carbon nanotubes are among the most attractive nanomaterials for a wide range of applications ranging from nanoelectronics to medical sensors. They can be imagined as the result of rolling a single graphene sheet into a tube.

Their properties vary widely with their diameter, what chemists call chirality - how symmetrical they are - and by how the graphene sheet is rolled.

The problem faced by researchers is that it is no longer possible to make high quality research samples of single-walled carbon nanotubes using the standard method. This was associated with the Carbon Center at Rice University, which used the high-pressure carbon monoxide (HiPco) gas-phase process developed by Nobel Laureate, the late Rick Smalley.

The demise of the Carbon Center in the mid-2010s, the divesting of the remaining HiPco samples to a third-party entity with no definite plans of further production, and the expiration of the core patents for the HiPco process, meant that this existing source of nanotubes was no longer an option.

Now however, a collaboration between scientists at Swansea University (Wales, UK), Rice University (USA), Lamar University (USA), and NoPo Nanotechnologies (India) has demonstrated that the latter's process and material design is a suitable replacement for the the Rice method.

Analysis of the Rice "standard" and new commercial-scale samples show that back-to-back comparisons are possible between prior research and future applications, with the newer HiPco nanotubes from NoPo Nanotechnologies comparing very favourably to the older ones from Rice.

These findings will go some way to reassure researchers who might have been concerned that their work could not continue as high-quality nanotubes would no longer be readily available.

Professor Andrew Barron of Swansea University's Energy Safety Research Institute, the project lead, said:
"Variability in carbon nanotube sources is known to be a significant issue when trying to compare research results from various groups. What is worse is that being able to correlate high quality literature results with scaled processes is still difficult".

Erstwhile members of the Smalley group at Rice University, which developed the original HiPco process, helped start NoPo Nanotechnologies with the aim of updating the HiPco process, and produce what they call NoPo HiPCO® SWCNTs.

Lead author Dr. Varun Shenoy Gangoli stated:
"It is in the interest of all researchers to understand how the presently available product compares to historically available Rice materials that have been the subject of a great range of academic studies, and also to those searching for a commercial replacement to continue research and development in this field."

Graphene gas sensors for real-time monitoring of air pollution

Posted By Graphene Council, Tuesday, January 7, 2020
Scientists at the National Physical Laboratory (NPL), working with partners from the Graphene Flagship, Chalmers University of Technology, the Advanced Institute of Technology, Royal Holloway University and Linköping University, have created a low-cost, low-energy consuming NO2 sensor that measures NO2 levels in real-time.

The World Health Organisation reported that 4.2 million deaths every year are a direct result of exposure to ambient air pollution such as NO2, SO2, NH3, CO2 and CO. One of the most dangerous pollutants, NO2 gas, is produced by burning fossil fuels e.g. in diesel engines. Significant portions of the population in large cities, specifically London, have been consistently exposed to NO2 levels above the legislated limit. Even at very low concentrations NO2 is toxic for humans, leading to breathing problems, asthma attacks and potentially causing childhood obesity and dementia.  

NPL and partners have developed a graphene-based NO2 detector that reports pollutant levels based on changes in its electrical resistance. The high sensitivity of graphene to the local environment has shown to be highly advantageous in sensing applications, where ultralow concentrations of absorbed molecules induce a significant response on the electronic properties of graphene. The unique electronic structure makes graphene the ‘ultimate’ sensing material for applications in environmental monitoring and air quality.  

NPL has developed and demonstrated the novel type of NO2 sensors based on different types of graphene. This low-cost and technologically simple solution uses simple chemiresistor approach and allows for measurements of the exceedingly low levels of NO2 e.g. below 10 ppb. 1 ppb is a concentration equal to a droplet of ink in 2 Olympic size swimming pools. According to the World Health Organisation’s guidelines the targeted level of NO2 pollution in cities is 21 ppb however, the typical average level in London is 30-40 ppb.    

There is a well-demonstrated global need for high sensitivity, low-cost, low-energy consumption miniaturised NO2 gas sensors to be deployed in a dense network and to be used to pinpoint and avoid high pollution hot spots. Such sensors operating in real-time can help to visualise pollution in urban areas with unprecedently high local resolution. 

Olga Kazakova, National Physical Laboratory (NPL) states: “Understanding the problem is the first step to solving the problem. If you only monitor certain junctions or roads for NO2 pollution, you do not get an accurate picture of the environment. In order to do this, a dense network must be set up to show the dynamically changing level of pollution through different times of day and year, so you can get to know the real level of critical exposure.” 

With the data provided by a dense network of graphene sensors, people could us an app to check how much NO2 pollution they might be exposed to on their planned route, and city councils could use this information to dynamically restrict and divert cars near schools and hospitals. This would enable governing bodies to adopt smart and flexible restrictive measures in specific areas recognised as being highly pollutive.

New Nanosensor Detects Microscopic Contaminants in Water

Posted By Graphene Council, Tuesday, November 19, 2019
Good things come in small packages. Sadly, so do bad things. That’s where Iowa State University’s (ISU) Department of Mechanical Engineering comes in.

Led by Dr. Jonathan Claussen, ISU researchers have used nanotechnology to develop a sensor that can detect organophosphates at levels 40 times smaller than the U.S. Environmental Protection Agency (EPA) recommendations. Organophosphates are certain classes of insecticides used on crops throughout the world to kill insects.

“It is important that we quantify insecticide runoff and drift so that we can characterize its long-term effects and find ways to minimize those effects.”

USDA’s National Institute of Food and Agriculture is supporting this research through a pair of Agriculture and Food Research Initiative grants totaling $573,000.

Claussen used the grants to develop Salt Impregnated Inkjet Maskless Lithography (SIIML), which uses an inkjet printer to create inexpensive graphene circuits with high electrical conductivity. He adds salts to the ink, which is later washed away to leave microsized divots or craters in the surface. This textured printed graphene surface is able to bind with pesticide-sensing enzymes to increase sensitivity during pesticide biosensing.

These sensors can detect contaminants as small as 0.6 nanometers (nM) in length, well below the EPA standard of 24 nM and Canada’s standard of 170 nM.

Claussen compares the graphene sensors to glucose test strips that diabetics use to monitor their blood. Both the glucose test strip and the graphene pesticide test strip monitor selected compounds through electrochemical means.

This technology can be adapted for field use to detect a wide range of samples, including pathogens in food and fertilizer in soil and water. The technology is so inexpensive, Claussen said, that sensors could be used across an entire farm field to monitor pesticides and fertilizers so that farmers could limit their use and apply only what is truly needed.

In addition to improving the environmental ecosystem, Claussen said that SIIML could improve food safety, from farm to fork.

“The sensors could be designed to detect pathogens in food processing facilities to prevent food contamination,” he said. “The sensors could also be used to monitor cattle diseases, for example, before physical symptoms are present. This technique could really be a game changer for a variety of in-field sensing applications that require low-cost but highly sensitive biosensors.”

Tetra Pak explores Graphene material for the food and beverage manufacturing industry

Posted By Graphene Council, Friday, October 18, 2019
Tetra Pak has joined the European Commission Graphene Flagship project as the exclusive representative from the packaging industry to explore possible future applications of graphene in food and beverage (F&B) manufacturing. 

Graphene is a carbon-based material, one of the thinnest known to mankind, one atom thick, while also being incredibly strong: around 200 times stronger than steel. It is an excellent conductor of heat, electricity and has a wide range of light absorption abilities. Graphene material could bring breakthrough innovations with unlimited potential for integration in almost any industry.

Prof Konstantin Novoselov, Physicist and Nobel Prize Winner said: ‘Graphene has the potential to revolutionise a range of processes and industries. Since Graphene’s first isolation in 2004, we have seen tremendous success and marketplace application of the material within electronics and automotive industries, I’m looking forward to the next phase of the Graphene Flagship and exploring potential innovations in the packaging industry.’

Sara De Simoni, VP, Equipment Engineering, Tetra Pak said: ‘Tetra Pak’s involvement with the European Graphene Flagship is one example of our ambition to drive innovation to the next level. It is a privilege to be the only representative from our industry in this research initiative and puts us at the cutting edge to address challenges through multidisciplinary research and development together with our industry partners.’

Tetra Pak is leading R&D in the packaging sector, exploring the potential graphene holds to unlock a range of new and revolutionary innovations for the F&B industry, including: 

Packaging material innovation – is being examined to see how graphene could offer coatings to reduce carbon footprint in packaging supply chain, graphene can also enhance the performance of current packaging materials, enable new functionality as well as increase recyclability.

Smart Packaging – with the development of smart packaging, graphene’s ultra-thin flexible sensors can be integrated to packages as data carriers for producers, retailers and consumers. Graphene sensors can also be smaller, lighter and less expensive than traditional sensors.

Next generation of equipment – exploring how graphene composites can be used to make equipment lighter and more energy efficient has the potential to reduce costs and energy consumption.  With only modifications needed to equipment over additional purchases, both time and money are saved.

Smart Insole Can Double As Lifesaving Technology For Diabetic Patients

Posted By Graphene Council, Monday, October 14, 2019
Updated: Tuesday, October 15, 2019
Stevens Institute of Technology has signed an exclusive licensing agreement with Bonbouton, giving the cutting-edge health and technology company the right to use and further develop a graphene sensing system that detects early signs of foot ulcers before they form so people living with diabetes can access preventative healthcare and confidently manage their health.

The smart insole, Bonbouton’s first product, can be inserted into a sneaker or dress shoe to passively monitor the foot health of a person living with diabetes. The data are then sent to a companion app which can be accessed by the patient and shared with their healthcare provider, who can determine if intervention or treatment is needed.

“I was inspired by two things—a desire to help those with diabetes and a desire to commercialize the technology,” said Bonbouton Founder and CEO Linh Le, who developed and patented the core graphene technology while pursuing a doctorate in chemical engineering at Stevens. Le came up with the idea to create an insole that could help prevent diabetic ulcers after several personal incidents lead him to pursue preventative healthcare.

Complications from diabetes can make it difficult for patients to monitor their foot heath. Chronically high levels of blood glucose can impair blood vessels and cause nerve damage. Patients can experience a lot of pain, but can also lose feeling in their feet. Diabetes-related damage to blood vessels and nerves can lead to hard-to-treat infections such as ulcers. Ulcers that don’t heal can cause severe damage to tissues and bone and may require amputation of a toe, foot or part of a leg.

Bonbouton’s smart insoles sense the skin’s temperature, pressure and other foot health-related data, which can alert a patient and his or her healthcare provider when an infection is about to take hold. This simplifies patient self-monitoring and reduces the frequency of doctor visits, which can ultimately lead to a higher quality of life.

Bonbouton, which is based in New York City, is currently partnering with global insurance company MetLife to determine how its smart insoles will be able to reduce healthcare costs for diabetic foot amputations. In 2018, Bonbouton also announced its technical development agreement with Gore, a company well known for revolutionizing the outerwear industry with GORE-TEX® fabric, to explore ways to integrate Bonbouton’s graphene sensors in comfortable, wearable fabric for digital health applications, including disease management, athletic performance and everyday use.

“We are interested in developing smart clothing for preventative health, and embrace the possibilities of how our graphene technology can be used in other industries,” said Le. “I am excited to realize the full potential of Bonbouton, taking a technology that I developed as a graduate student at Stevens and growing it into a product that will bring seamless preventative care to patients and save billions of dollars in healthcare costs.”

New health monitors are flexible, transparent and graphene enabled

Posted By Graphene Council, Wednesday, September 18, 2019

New technological devices are prioritizing non-invasive tracking of vital signs not only for fitness monitoring, but also for the prevention of common health problems such as heart failure, hypertension, and stress related complications, among others. Wearables based on optical detection mechanisms are proving an invaluable approach for reporting on our bodies inner workings and have experienced a large penetration into the consumer market in recent years.

Current wearable technologies, based on non-flexible components, do not deliver the desired accuracy and can only monitor a limited number of vital signs. To tackle this problem, conformable non-invasive optical-based sensors that can measure a broader set of vital signs are at the top of the end-users’ wish list.

In a recent study published in Science Advances ("Flexible graphene photodetectors for wearable fitness monitoring"), ICFO researchers have demonstrated a new class of flexible and transparent wearable devices that are conformable to the skin and can provide continuous and accurate measurements of multiple human vital signs. These devices can measure heart rate, respiration rate and blood pulse oxygenation, as well as exposure to UV radiation from the sun.

While the device measures the different parameters, the read-out is visualized and stored on a mobile phone interface connected to the wearable via Bluetooth. In addition, the device can operate battery-free since it is charged wirelessly through the phone.

“It was very important for us to demonstrate the wide range of potential applications for our advanced light sensing technology through the creation of various prototypes, including the flexible and transparent bracelet, the health patch integrated on a mobile phone and the UV monitoring patch for sun exposure. They have shown to be versatile and efficient due to these unique features”, reports Dr. Emre Ozan Polat, first author of this publication.

The bracelet was fabricated in such a way that it adapts to the skin surface and provides continuous measurement during activity (see Figure 1). The bracelet incorporates a flexible light sensor that can optically record the change in volume of blood vessels, due to the cardiac cycle, and then extract different vital signs such as heart rate, respiration rate and blood pulse oxygenation.

Secondly, the researchers report on the integration of a graphene health patch onto a mobile phone screen, which instantly measures and displays vital signs in real time when a user places one finger on the screen (see Figure 2). A unique feature of this prototype is that the device uses ambient light to operate, promoting low-power-consumption in these integrated wearables and thus, allowing a continuous monitoring of health markers over long periods of time.

ICFO’s advanced light sensing technology has implemented two types of nanomaterials: graphene, a highly flexible and transparent material made of one-atom thick layer of carbon atoms, together with a light absorbing layer made of quantum dots. The demonstrated technology brings a new form factor and design freedom to the wearables’ field, making graphene-quantum-dots-based devices a strong platform for product developers.

 

Dr. Antonios Oikonomou, business developer at ICFO emphasized this by stating that “The booming wearables industry is eagerly looking to increase fidelity and functionality of its offerings. Our graphene-based technology platform answers this challenge with a unique proposition: a scalable, low-power system capable of measuring multiple parameters while allowing the translation of new form factors into products.”

Dr. Stijn Goossens, co-supervisor of the study, also comments that “we have made a breakthrough by showing a flexible, wearable sensing system based on graphene light sensing components. Key was to pick the best of the rigid and flexible worlds. We used the unique benefits of flexible components for vital sign sensing and combined that with the high performance and miniaturization of conventional rigid electronic components.”

Finally, the researchers have been able to demonstrate a broad wavelength detection range with the technology, extending the functionality of the prototypes beyond the visible range. By using the same core technology, they have fabricated a flexible UV patch prototype (see Figure 3) capable of wirelessly transferring both power and data, and operating battery-free to sense the environmental UV-index. continuous monitoring of health markers over long periods of time.

The patch operates with a low power consumption and has a highly efficient UV detection system that can be attached to clothing or skin, and used for monitoring radiation intake from the sun, alerting the wearer of any possible over-exposure.

“We are excited about the prospects for this technology, pointing to a scalable route for the integration of graphene-quantum-dots into fully flexible wearable circuits to enhance form, feel, durability, and performance”, remarks Prof. Frank Koppens, leader of the Quantum Nano-Optoelectronics group at ICFO. “Such results show that this flexible wearable platform is compatible with scalable fabrication processes, proving mass-production of low-cost devices is within reach in the near future.”

World’s smallest accelerometer points to new era in wearables, gaming

Posted By Graphene Council, Wednesday, September 11, 2019
Updated: Friday, September 6, 2019
In what could be a breakthrough for body sensor and navigation technologies, researchers at KTH have developed the smallest accelerometer yet reported, using the highly conductive nanomaterial, graphene.

Each passing day, nanotechnology and the potential for graphene material make new progress. The latest step forward is a tiny accelerometer made with graphene by an international research team involving KTH Royal Institute of Technology, RWTH Aachen University and Research Institute AMO GmbH, Aachen.

Among the conceivable applications are monitoring systems for cardiovascular diseases and ultra-sensitive wearable and portable motion-capture technologies.

For decades microelectromechanical systems (MEMS) have been the basis for new innovations in, for example, medical technology. Now these systems are starting to move to the next level – nano-electromechanical systems, or NEMS.

Xuge Fan, a researcher in the Department for Micro and Nanosystems at KTH, says that the unique material properties of graphene have enabled them to build these ultra-small accelerometers.

“Based on the surveys and comparisons we have made, we can say that this is the smallest reported electromechanical accelerometer in the world,” Fan says. The researchers reported their work in Nature Electronics.

The measure by which any conductor is judged is how easily, and speedily, electrons can move through it. On this point, together with its extraordinary mechanical strength, graphene is one of the most promising materials for a breathtaking array of applications in nano-electromechanical systems.

“We can scale down components because of the material’s atomic-scale thickness, and it has great electrical and mechanical properties,” Fan says. “We created a piezoresistive NEMS accelerometer that is dramatically smaller than any MEMS accelerometers available today, but retains the sensitivity these systems require.”

The future for such small accelerometers is promising, says Fan, who compares advances in nanotechnology to the evolution of smaller and smaller computers.

“This could eventually benefit mobile phones for navigation, mobile games and pedometers, as well as monitoring systems for heart disease and motion-capture wearables that can monitor even the slightest movements of the human body,” he says.

Other potential uses for these NEMS transducers include ultra-miniaturized NEMS sensors and actuators such as resonators, gyroscopes and microphones. In addition, these NEMS transducers can be used as a system to characterize the mechanical and electromechanical properties of graphene, Fan says.

Max Lemme, professor at RWTH, is excited about the results: "Our collaboration with KTH over the years has already shown the potential of graphene membranes for pressure and Hall sensors and microphones. Now we have added accelerometers to the mix. This makes me hopeful to see the material on the market in some years. For this, we are working on industry-compatible manufacturing and integration techniques."

Grolltex Graphene Closes Oversubscribed Private Placement Financing Round

Posted By Graphene Council, Wednesday, September 11, 2019
Updated: Tuesday, September 10, 2019

Grolltex (named for ‘graphene-rolling-technologies’) is the largest commercial producer of single layer, ‘electronics grade’ graphene and graphene sensing materials in the U.S. They have announced that it has closed a non-brokered, oversubscribed private placement financing, in the form of a convertible note, with local area private investors. 

The gross proceeds of the private placement will be used for general working capital purposes and for increasing the capacity and quality testing capabilities of the company’s production facility in San Diego, California.


The company is focused on delivering inexpensive and enabling solutions to advanced nano-device and graphene sensor makers by fabricating the highest quality single layer graphene attainable, via chemical vapor deposition (or ‘CVD’).

The company is now capable of producing monolayer graphene sensors on large area plastic sheets at a cost of pennies per unit, in a high throughput and sustainable way.  Further, Grolltex is helping customers that currently produce their graphene sensors on silicon wafers, to transition that production capacity to making their sensors on large area sheets of biodegradable plastic instead, at a >100X cost savings. 

Monolayer graphene films are today seen as the most promising futuristic sensing materials for their combination of surface to volume ratio (the film is only one atom thick) and conductivity (the most conductive substance known at room temperature). Markets that are commercializing advanced sensors made of graphene include DNA sensing and editing, new drug discovery and wearable bio-monitors for glucose sensing and autonomous blood pressure monitoring via patches or watch-like wearable bracelet devices.

No securities were issued and no cash was paid as bonuses, finders’ fees, compensation or commissions in connection with the private placement.
