Figure 1: Human Peizoelectric Supercapacitors Requirements

The initial Industry Engagement Grant entitled “Piezoelectric Supercapacitors for Self-Powered Medical Implants” was awarded to Professor Cameron Brown, Associate Professor Deepak Dubal, Dr. Hong Duc Pham and the Chief Scientific Officer of GMG, Dr. Ashok Kumar Nanjundan.

Most modern electrical medical implants (such as pacemakers, insulin delivery pumps and as shown in the figure 1) actively regulate or replace bodily functions, and thus require batteries capable of reliably functioning for many years without failure. Implanted batteries typically require secondary surgeries for replacement, incurring significant inconvenience to patients in the forms of high costs, discomfort, and the risk of infection.

This project aims to develop capability for self-charging medical implants by engineering a novel power unit called a “Piezo-Supercapacitor”, which can harvest human body-motions, converting that energy into electricity and store it, in a single unit. The concept is based on a mechanism that hybridizes the two processes into one, where the mechanical energy is directly converted and simultaneously stored as electrochemical energy without going through the intermediate step of converting into electricity.

About GMG

GMG is an Australian based clean-tech disruptive company listed on the Canadian 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 also 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.
