Implanted medical devices are battery powered, which means the battery has to be changed from time to time.  Realizing the battery problem, mechanical engineering professor Yong Shi, at the Stevens Institute of Technology, has devised a nanogenerator that collects energy from fluid (e.g. blood) movement inside the body.  It does this through piezoelectric nanofibers.  Among other things, this raises thoughts of nano-robots in the blood stream, collecting data and transmitting it to an external wireless receiver for analysis.      MORE
