This project aims to investigate the use of piezoelectric materials (that is, materials that can generate electricity upon bending or pressing) as part of self-powered supercapacitors. Piezoelectric polymers will be explored for their potential use as innovative energy harvesting devices to be used in Australia’s banknote security industry.

Prof Ellis’ research group has been working closely with the Reserve Bank of Australia to transform piezoelectric polymers into devices to generate electricity in future generations of polymeric banknotes.

The specific aims of this program are to:

  • Work on the synthesis of new classes of piezoelectric fluoropolymers with enhanced polarisation.
  • Investigate and improve the electromechanical conversion efficiencies of the synthesised polymers.
  • Develop novel processing techniques such as 3D printing for the optimal energy harvesting capabilities using a variety of nanomaterials and other internal templates.

These advanced capabilities for polymeric piezoelectric materials will allow us to create new classes of sustainable energy harvesting materials with further uses in powering wearable electronics, implantable electronic devices and point-of-care diagnostic tools.
