Heartbeat may power Future Mobiles...

A good news for all those who are tired of frequently charging their mobiles. Researchers from Southampton University have developed a technology that will be able to harness your heartbeat to power your cell phone.British researchers have developed a miniature generator that can produce electricity from vibrations in the surrounding environment, reports the Telegraph.The new find is supposed to prove a boon for people with pacemakers. Initially developed for use in industrial machinery, the scientists are now tweaking the design so it can be used to power pacemakers off a beating heart. It would allow patients to avoid surgery to replace batteries in their pacemaker.
However, researchers also hope that they will eventually be able to use the highly-efficient generators to power other portable wireless devices, including mobiles and MP3 players. It would mean that mobile users could charge their phone by simply keeping it in their breast pocket near their heart.
The miniature generator works on the same principles as a kinetic powered watch, which uses the movement of a coil between magnets to produce an electrical current. The researchers at Southampton and their company Perpetuum have found that they can tune the device to a particular frequency of movement so it will produce far more power than the devices found in watches.The researchers are also hoping to use their technology to scavenge energy from the vibrations of bridges and roads.
