[ Watch the Video: Harnessing Everyday Motion To Power Mobile Devices ] Lee Rannals for redOrbit.com - Your Universe Online Researchers at the 247th National Meeting & Exposition of the American Chemical Society (ACS) presented the possibilities of harnessing motion to power mobile devices. The team is setting out to transform the way scientists look at mechanical energy. Conventional energy sources rely on old science that requires power plants and a grid to distribute...

Energy Converted And Stored In Single Unit Using Self-charging Power Cell

Researchers have developed a self-charging power cell that directly converts mechanical energy to chemical energy, storing the power until it is released as electrical current. By eliminating the need to convert mechanical energy to electrical energy for charging a battery, the new hybrid generator-storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries. At the heart of the self-charging power cell is a piezoelectric membrane that...

Self-powered nanosensors By combining a new generation of piezoelectric nanogenerators with two types of nanowire sensors, researchers have created what are believed to be the first self-powered nanometer-scale sensing devices that draw power from the conversion of mechanical energy. The new devices can measure the pH of liquids or detect the presence of ultraviolet light using electrical current produced from mechanical energy in the environment. Based on arrays containing as many as 20,000...

PHILADELPHIA -- If you already have a little spring in your step, a team of biologists at the University of Pennsylvania would like to them to good use by adding a few more springs in the form of a power-generating backpack. Details of their prototype "Suspended-load Backpack" were announced today in the journal Science. The device converts mechanical energy from walking into electricity "“ up to 7.4 Watts "“ more than enough energy to power a number of portable electronic...
