So I was on the morbid tube journey toward central today and picked up the metro..as you do; I read that soon the beat of my heart will be powering my iPod… Well I don’t really know what to say about that to be honest- it’s something that could revolutionize technology, but it sounds kind of scary no? Apparently it’s called ‘nanogeneration’ and it has already been used to power LCD displays and transmit radio signals! Read the full article after the cut.

According to my favourite website (wikipedia), a nanogenorator: is an energy harvesting device converting the external kinetic energy into an electrical energy based on the energy conversion by nano-structured piezoelectric material.
The nanogenerator has already been used to power LCD displays and transmit radio signals but it is thought that we could soon be listening to our favourite songs without an AA battery or charger in sight. Hailed as a milestone, the tiny chip works by using zinc oxide nanowires so small that 500 could fit in a human hair. When they are strained or flexed, electricity is produced – meaning any body movement from the pinch of a finger to a beating heart can generate power.
‘Our nanogenerators are poised to change lives in the future. Their potential is limited only by one’s imagination,’ said Dr Zhong Lin Wang, who led the research at the Georgia Institute of Technology. Five nanogenerators working together can produce three volts, the equivalent power of two AA batteries and Dr Wang claims the list of electronic products that could eventually benefit is endless. ‘While a few volts may not seem like much, additional nanowires and more nanogenerators, stacked together, could produce enough energy for powering an iPod or charging a mobile phone,’ he said.
