One of the most crucial yet unpopular technology is battery tech. A company called MicroGen Systems which develops battery technology for small small and low power consuming sensors, has created a new type of battery which charges itself by harnessing the power of vibrations.
The generator of this little battery contains a cantilever which vibrates back and forth, and this mechanical energy of the motion is converted into electric energy. These batteries can be used on sensors which are mounted on cars,TMPS system which monitors the tire pressure of the car.So as the car moves, the vibration of the car is used to power the sensor. The usage life of these batteries is like the vehicle itself. These are still under development and we are expecting to see a great deal of contribution from this technology.
