It’s every mobile journalists worst nightmare; you’re filming a march, taking a photo of a mugging or tweeting your most hilarious twit yet and your phone runs out of battery.
There’s no point in searching for a power point or trekking home for your charger because, by then, the moment will be well and truly gone.
But, if scientific research is to be believed, we won’t be fearing the flashing of low battery for much longer.
Those brainiacs have developed a minute chip that can produce power by using the body’s movement – thanks to something called ‘nanotechnology’. Don’t ask us. Anyway they are saying this could soon enable you to recharge your mobile phone by simply putting it closer to your heart.
Dr Zhong Lin Wang, who led the research at the Georgia Institute of Technology, 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.”
For the nreds among you, the technology basically works by using zinc oxide nanowires that produce electricity when they are strained. This means the slightest movement (like walking or even a heartbeat) can generate power.
Apparently the device is far more powerful than previous versions, which means that scientists can unleash the technology upon the world soon.
“If we can sustain the rate of improvement, the nanogenerator may find a broad range of other applications that require more power,” said Dr Wang.
With these rapid advancements it looks like we’ll be able to use this technologyin a heartbeat (sorry).
