If you’re worried how all that implantable technology you’ll have in your body is going to power itself, the answer may lie with Georgia Tech. “Georgia Tech researchers used zinc oxide wires that scratch against an electrode to generate a current, clearly showing potential for use within the constantly moving body.” The zinc wires rubbing had previously caused serious wear and tear in former experiments (not to mention the fact that zinc dissolves in water aka your body) so the team developed a more “robust” version of the device with added packaging film to protect the zinc wires.
Although the size in the photo is quite large, they believe it will be easy to scale the wires down to the much smaller size of three to five microns in diameter and 300 microns in length (the dot at the end of this period is about 615 microns wide). The only thing they’re waiting for is for production to begin and possibly some hefty investments I’m sure.
The development of body-powered energy devices has been on fire this last year. It seems that the future of devices are in the human body itself. Heat and movement can all be converted to energy to power all the little gadgets we get into our hands, from cellphones to body monitors. Having an implantable power generator makes the most sense in that batteries wouldn’t have to be replaced, and at least maintenance of such devices would be at a minimum.
How far are we from implantable self-powered devices? Some would say we’re almost there and I’d have to agree. The next few years may see implementation, maybe two years before we start seeing it in the consumer world.
