Can you imagine a cellphone that never sees the low battery warning and what if soon, your heartbeat ‘could recharge your mobile phone‘? If scientists are to be believed, then the next generation Apple iPhone 5, future iPods, Android smartphones and virtually any other hand-held gadgets could be charged with your own heartbeat — no battery hassles anymore!
Termed as “Nanogenerators“, these tiny chips can generate power by using the body’s own movement, a technology which could soon enable you to recharge your iPhone 5 by just holding closer to your heart!
A team of scientists led by Dr. Zhong Lin Wang from the Georgia Institute of Technology, who were behind the invention hoped that as the nanotechnology used in the chip evolves, it could lead to electronics which don’t require batteries or mains power. And that this ground-breaking power harvesting technology could replace conventional batteries in about five years.
At the National Meeting & Exposition of the American Chemical Society, Wang’s team demonstrated the ability of their proto-type device, using it to power LCD screens and even transmit a radio signal.
Wang’s new power harvesting device is thousands of times more powerful than current power sources. “If we can sustain the rate of improvement, the nanogenerator may find a broad range of other applications that require more power,” he said.
“This development represents a milestone toward producing portable electronics that can be powered by body movements without the use of batteries or electrical outlets. Our nanogenerators are poised to change lives in the future. Their potential is only limited by one’s imagination“, he went on to add.
So far, five generators stacked together can create the same amount of voltage in two AA batteries. With time, Dr. Wang hopes that by stacking more of these microscopic nanogenerators on top of one another (500 nanowires can fit on a stand of human hair), the tech can create enough energy to power iPhones, iPods and cellphones in the future. Wang expects his nanogenerators to be in stores within 5 years.
Interesting technology innovation, right? I mean, who wouldn’t want get rid of the charger and the slavery to rely on the mains power outlet every now and then? And who wouldn’t cherish an iPhone 5 that is ‘truly mobile‘?
