Abstract(Figure Presented) A nanogenerator based on a single piezoelectric fine wire producing an alternating current (AC) is successfully used for the harvesting of biomechanical energy under in vivo conditions. We demonstrate the implanting and working of such a nanogenerator in a live rat where it harvests energy generated by its breathing or heart beating. This study shows the potential of applying these nanogenerators for driving in vivo nanodevices. © 2010 WILEY-VCH Verlag GmbH & Co. KCaA, Weinheim.
