NEC working on battery-less remote
| |
Posted on Thursday, November 19 2009 @ 18:42:31 CET by Thomas De Maesschalck |
NEC and Soundpower are jointly developing a battery-less remote that will turn the weak vibrations from button presses into power. The company says this project has been in development since December 2006, they expect it will be ready for implementation in consumer electronics by 2011.
The remote control was realized by combining (1) a vibration-based power generation device developed by Soundpower, (2) NEC Electronics' microcomputer supporting RF remote controls that use radio waves with a frequency band ranging from several tens of MHz to several GHz to transmit and receive data and (3) a power supply control technology that drives electronic circuits with a small amount of electricity.
