Personal Micro-Generator Feeds of Body Vibrations
Steve Beeby, an engineer at the University of Southampton in the UK led a team that has developed a micro generator that converts 30% of environmental kinetic energy into power. The design is based on accelerometers and uses a few magnets that wobble against each other with vibration and motion that generates electricity. The prototype design is a mere 7mm x 7mm x 8.5mm and could be strategically placed in clothing or even implanted to generate power for a variety of low power devices including LED lighting, pacemakers, and eventually phones, music players, and pdas. The potential of this is fantastic - have a few micro-generators, a few batteries, and a few solar cells embedded in your favorite jacket or shirt, and you'll have power for your personal electronics and lighting systems, plus keep your ticker going if you need it!
