Heartbeats could power medical implants

Currently, medical implants in one’s body often requires a battery of sorts to keep it going, but what happens when those said implants run out of juice? Boffins at Georgia Tech are currently giving the Muscle-Driven In Vivo Nanogenerator idea a go on lab rats, where a tiny nanowire will be used to convert the motion of flexing muscles into electric current using piezoelectric energy. While the amount of juice generated is negligible at the moment, said group of scientists are working to bunch together an array of nanowires so that one’s movement is able to generate enough electricity to run a pacemaker. Hopefully the efficiency level of such a device will be insanely high, otherwise during the better 8 hours of a day when someone spends sleeping, there will be minimal movement which might not be enough generate electricity.
