New type of bioegradable nanogenerator for use inside the body does not need external power source

(Phys.org)—A team of researchers with the National Center for Nanoscience and Technology and Beihang University, both in China, has developed a biodegradable triboelectric nanogenerator for use as a life-time designed implantable power source in an animal body. In their paper published in the journal Science Advances the team describes their nanogenerator, its possible uses and the ways it can be tweaked for use in different applications.
