A vibration powered generator is a type of transducer that converts kinetic energy derived from ambient vibration to electrical energy.
Magnets wobbling on a cantilever are sensitive to even small vibrations and generate microcurrents by moving relative to conductors due to Faraday's law of induction. By developing a miniature device of this kind in 2007, a team from the University of Southampton made possible the planting of such a device in environments that preclude having any electrical connection to the outside world. Sensors in inaccessible places can now generate their own power and transmit data to outside receivers.[1]
Implants in heart muscles can use the heart's movement to generate sufficient voltage to act as a pacemaker, doing away with the necessity for regular battery replacements.[1] Sensors placed in remote parts of a space shuttle or airliner can transmit data to a central receiver, such as a black box, even in the event of a total power failure. The pressure and temperature of wheels on a trailer could be monitored by placing sensors on the inside of the tyre. Factories producing any type of merchandise will benefit from being able to place maintenance-free sensors at all critical points.
