NEC Electronics and Japanese company Soundpower have developed a TV remote control that works without the need for batteries.
When a user presses a button on the remote, to change the channel or turn the volume up or down a small amount of electricity is generated through vibrations, the energy is then used to power the remote and complete the desired function.
According to NEC, the electricity that is generated by the vibrations is enough to turn the TV on and off, as well as change the channel of increase or decrease the volume.
The Battery Free TV Remote Control is just in the early prototype stages at the moment, but both companies intend to start marketing the technology to TV makers next year, so who knows we could see our new TVs in the next few years arriving with battery free remote controls.
