| Finger tap charges device |
| THE AUSTRALIAN NATIONAL UNIVERSITY |
A simple tap from your finger may be enough to charge your portable device, thanks to a discovery made at RMIT University and ANU. Dr Simon Ruffell from the ANU Research School of Physics and Engineering and Dr Madhu Bhaskaran and Dr Sharath Sriram from RMIT University have used nanotechnology to convert mechanical pressure into electricity. The breakthrough was achieved by combining piezoelectrics, materials that convert pressure into electricity, with thin film technology, the foundation of microchip manufacturing. The use of piezoelectrics means that portable devices with touch screens like iPads and iPhones could be recharged through everyday activities like typing. It also means that in future pacemakers could be powered by an individual wearer’s blood pressure. |
