Queensland University of Technology (QUT) – Centre for Biomedical Technologies (CBT) and GMG was successful in the application for an Industry Engagement Grant.
Graphene Manufacturing Group Ltd (GMG) has a long-term collaboration with A/Prof. Deepak Dubal and QUT and this project is another step towards their strong commitment to real-world implications.
The Industry Engagement Grant entitled Piezoelectric Supercapacitors for Self Powered Medical Implants was awarded to Prof Cameron Brown, A/Prof Deepak Dubal (MCR), Dr. Hong Duc Pham (ECR), Dr. Ashok Kumar Nanjundan.
The project aims to develop self-charging medical implants by engineering a novel power unit called “Piezo-Supercapacitor”, which can harvest human body motions into electricity and store them in a single unit. The concept, we introduce here is based on a fundamental mechanism that directly hybridizes the two processes into one, in which the mechanical energy is directly converted and simultaneously stored as electrochemical energy without going through the intermediate step of first converting into electricity.
To achieve this objective, innovative piezo-supercapacitors will be developed by using piezoelectric biological proteins (collagen) as separator and GMG graphene-based electrode materials in collaboration with industry partner Graphene Manufacturing Group Ltd. The piezoelectric potential from the collagen film created by mechanical straining acts as a charge pump to drive ions to migrate towards respective electrodes accompanying charging reactions at electrodes. This new technology can be applied to manufacture self-powered medical implants, which will eliminate risks to patient’s life and save large costs related to battery- replacement, and surgery.
By building safe, reliable, and high-performance power sources for medicine, this technology will enable a new generation of active implants that can monitor health, detect disease, and administer treatment.
GMG is an Australian based clean-tech disruptive company listed on the TSXV (TSXV:GMG) that produces graphene and hydrogen by cracking methane (natural gas) instead of mining graphite. By using the company’s proprietary process, GMG can produce high quality, low cost, scalable, ‘tuneable’ and no/low contaminant graphene – enabling demonstrated cost and environmental improvements in a number of world-scale planet-friendly/clean-tech applications. Using this low input cost source of graphene, the Company is developing value-added products that target the massive energy efficiency and energy storage markets.
The Company is pursuing additional opportunities for GMG Graphene, including developing next-generation batteries, collaborating with world-leading universities in Australia, and investigating the opportunity to enhance the performance of lube oil, biodiesel and diesel fuels.
