Following five years or research, a new way to power conventional electronic devices that harnesses energy from the environment has been revealed.
Researchers at Georgia Tech, US, have discovered that powering electronic devices with nanoscale generators that have mechanical energy from the environment can be possible.
According to the research, the mechanical energy can come from a heartbeat, compressing the generator between two fingers or even the rustling of a shirt.
The process, which works by using an array of tiny nanowires, will never manage to produce large amount of electricity for conventional purposes but could be used to power portable devices such as iPods and MP3 players, healthcare devices and environmental monitoring devices.
