Tiny Generator Runs Off Vibrations

Warbothong writes "Researchers at Southampton University in the UK have developed a tiny generator that uses local vibrations to output microwatts of power. The device is smaller than one cubic centimeter. It shows promise as an alternative to batteries for applications where frequent battery replacement would not be feasible. The devices are currently being used in industry where 'there is the potential for embedding sensors in previously inaccessible locations,' but its creators imagine it could be used in devices such as pacemakers, where the beating of the heart would produce ample movement to power the magnetic mechanism."
