Have you got good vibrations on your MP3 player?
December 18 2009
Research developers based at the University of Bristol are working on new technology which will power up by the vibration the item picks up from its surroundings.
The technology, which would be ideal for MP3 players, is based on vibration energy harvesting equipment which utilises a spring and mass mechanism, which captures the resonance given off in the form of small vibrations, which is then amplified to become a usable energy.
At present, tests are showing that this method can harness movement and convert it to energy. First working trials are using low frequencies of the vibration, but it is hoped that higher ranges of frequency can be utilised, which could potentially will generate more power.
As well as MP3 players, phones could be charged in the same fashion and even heart monitors. The test equipment can currently pick up vibrations ranging from choppers flying close by, to passing trains, to even some human body movements.
It is hoped that in 5 years time, we shall see various consumer products powered by these means, with the possibilities of larger items like cars being powered expected in 10 years time.
