Using brainwaves to command and control autonomous vehicles

Posted By Graphene Council, Wednesday, August 26, 2020
Researchers at the University of Technology Sydney (UTS) are using smart sensors and advanced brain signal decoders to improve communication between human brains and robots.

A team led by Distinguished Professor CT Lin and Professor Francesca Iacopi will embark on a two-year project with the Department of Defence to examine how cutting-edge technologies could use brainwaves to command and control autonomous vehicles.

Distinguished Professor CT Lin, Director of The UTS Computational Intelligence and Brain Computer Interface Centre, is a leading researcher in brain computer interfaces (BCI). 

An expert in wearable and wireless devices, Professor Lin combines human physiological information with artificial intelligence (AI) to develop advanced monitoring and feedback systems.

“I want to improve the flow of information from humans to robots, so humans can make better informed decisions,” said Professor Lin.

An internationally-recognised expert in nanotechnology, Professor Francesca Iacopi will design and produce the graphene-based smart sensors required for the wearable device.  

Professor Iacopi has developed a novel method to embed graphene-based microdevices on silicon wafers. The process can be adapted for large-scale manufacturing. 

Professor Iacopi said most graphene synthesis methods are not compatible with semiconductor technologies, precluding miniaturised applications. 

“The new synthesis I developed will help obtain graphene from sources that make it more accessible and affordable.”

The project has received $1.2 million in funding from the Defence Innovation Hub.

The innovative technology has potential applications across multiple sectors including MedTech and biotechnology.

Novel approach improves graphene-based supercapacitors

Posted By Graphene Council, Tuesday, August 4, 2020
This is creating an exponential need for advanced energy storage technologies -- reliable and maintenance-free batteries and supercapacitors (SC) with high power density capability as storage devices. Supercapacitors are prominent candidates to meet this need due to their environmentally friendly and long cyclability characteristics.

Researchers from the Integrated Nano Systems Lab (INSys Lab), in the Centre for Clean Energy Technology, have been working on a pathway to improve the performance of supercapacitors, and meet that demand for increased storage capacity.

Dr Mojtaba Amjadipour and Professor Francesca Iacopi (School of Data and Electrical Engineering) and Dr Dawei Su (School of Mathematical and Physical Sciences) describe their cutting-edge work in the July 2020 issue of the journal Batteries and Supercaps. The prominence given to Graphitic-Based Solid-State Supercapacitors: Enabling Redox Reaction by In Situ Electrochemical Treatment -- designated a Very Important Paper with front coverage placement -- signifies just how innovative their research is in developing alternate ways to extend storage capacity.

Dr Iacopi said the multi-disciplinary approach within the team was beneficial in discovering what she says is a simple process.

"This research has originated from our curiosity of exploring the operation limits of the cells, leading us to unforeseen beneficial results. The control of this process would not have been possible without understanding the fundamental reasons for the observed improvement, using our team's complementary expertise."

Traditionally, supercapacitors are fabricated with liquid electrolytes, which cannot be miniaturised and can be prone to leakage, prompting research into gel-based and solid-state electrolytes. Tailoring these electrolytes in combination with carbon-based electrode materials such as graphene, graphene oxide, and carbon nanotubes is of paramount importance for an enhanced energy storage performance.

Graphene or graphitic carbon directly fabricated on silicon surfaces offers significant potential for on-chip supercapacitors that can be embedded into integrated systems. The research insights indicate a simple path to significantly enhance the performance of supercapacitors using gel-based electrolytes, which are key to the fabrication of quasi-solid-(gel) supercapacitors.

"This approach offers a new path to develop further miniaturized on-chip energy storage systems, which are compatible with silicon electronics and can support the power demand to operate integrated smart systems," Dr Iacopi said.
