Sydney:
Thanks to a new discovery, a simple tap from your finger may be
enough to charge portable devices like mobile phones and iPads.
Simon Ruffell from the Australian National University and Madhu
Bhaskaran and Sharath Sriram from Royal Melbourne Institute of
Technology University have used nanotechnology to convert
mechanical pressure into electricity.
The breakthrough was made by combining piezoelectrics, materials
capable of turning pressure into electricity, with thin film
technology -- the basis of microchip manufacturing, according to a
Melbourne Institute statement.
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.
