Tiny generator developed by scientists

Scientists at the University of Southhampton have successfully developed a minuscule generator that powers devices in lieu of batteries, especially in cases where a battery replacement procedure is next to impossible. It will first be tested on wireless sensors before being moved into more important areas such as powering heart pacemakers. According to test results, this new generator is 10 times more efficient than similar devices, despite measuring less than a cubic centimeter in size. It works by utilizing vibrations around it to make magnets on a cantilever in the confines of the device to wobble, and thus generating power. Guess this would make a great self-powered medical implant if the need ever arises.
