Researchers at Curtin University and UNSW Sydney have discovered a way to short circuit the need for batteries in small electronics.
The team was able to show that the mechanical vibrations created from sliding metal along a silicon surface can be converted into a continuous electrical current.
Lead researcher and PhD candidate from Curtin University Stuart Ferrie says the discovery could transform the medical and environmental industries.
“Self-powered electronics would offer a potential solution when it is difficult to replace or recharge a battery, such as in life-critical medical implants, pacemakers, or GPS tracking devices used in animals,” he said.
Co-author Dr Simone Ciampi from Curtin University said the research findings could lead to a wide range of applications.
“Creating autonomous power supplies is the way of the future and will have significant benefits for a range of different industries that currently rely on batteries or solar panels for recharging,” she said.
“The full spectrum of creating these types of self-powered electronics is still relatively unclear and further research and testing is needed, but this work provides explicit evidence that it is possible to create a continuous source of direct-current electricity.”
