ANU cracks piezoelectrical battery charging

ANU have announced a fascinating breakthrough to generate electricity through mechanical power without needing magnetic dynamos.

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 made by combining piezoelectrics, materials capable of turning pressure into electricity, with thin film technology, the basis 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.

@qbngeek – If you’re going to make a snide remark about something then it’s probably a good idea to inform yourself beforehand. Take 30 seconds to actually read the linked article and you’ll notice that the ANU are not laying claim to inventing piezoelectric film nor using said film to charge batteries.

Damn those cyclists get up early.

Looks to me suspiciously like the phone charging t-shirts that are in the news at the moment. They are using a piezoelectric film to charge phones via the vibration made by musical frequencies. They will be trialled at Glastonbury in the next few days.

Doesn’t really seem like ANU is onto anything new here.
