One of the first accessories I got for my RAZR phone was a Bluetooth Headset.  I frequently use a hands-free system when I’m driving, but the classic corded earpiece with the dangling microphone always got tangled up as I reached around the car or turned my head to check blind spots.  Not to mention they usually weren’t really hands-free, as you still had to grab the phone to do any dialing with it.  So after some research I bought a simple Jabra BT350 to try out, and I continue to be happily surprised with how well it performs.

After using it for a few days, I had an odd thought.  How far away are we from using technology very similar to this to create a literal Bluetooth headset? By this I mean created a dental implant that can operate as a universal headset for your cellphone.  Replace a tooth (or supplement it with a Cap) to operate as the Bluetooth Headset and sync it with your phone. It seemed neat, but the obvious first problem was how to recharge it?  Wouldn’t want to be pulling it in and out to recharge, but I didn’t know of any way to really (safely) recharge it inside your mouth either.

Yesterday, on Slashdot, I found an answer.  Georgia Tech has created a small nanogenerator capable of generating enough power to recharge small devices with motion as small as moving your feet, and small enough to be implanted in a shoe.  A bluetooth headset doesn’t take much power (The BT350 holds enough charge for somewhere around 600hours standby, and well over 40 hours of talk time, and I’ve tested it enough to believe it’s true), and since you obviously move your mouth to talk, that should create ample charge to sustain the device.
