A simple tap from your finger may be enough to charge your portable device thanks to a discovery made at RMIT University and Australian National University.

In a crucial step towards the development of self-powering portable electronics, researchers at RMIT University in Melbourne have for the first time characterised the ability of piezoelectric thin films to turn mechanical pressure into electricity. The pioneering result is published in the 21 June Issue of the leading materials science journal, Advanced Functional Materials.

Lead co-author Dr Madhu Bhaskaran said the research combined the potential of piezoelectrics – materials capable of converting pressure into electrical energy – and the cornerstone of microchip manufacturing, thin film technology. “The power of piezoelectrics could be integrated into running shoes to charge mobile phones, enable laptops to be powered through typing or even used to convert blood pressure into a power source for pacemakers – essentially creating an everlasting battery,” she said.
