Replacing batteries by nanogenerators (NGs) in small consumer electronics is one of the goals in the emerging field of self-powered nanotechnology. We show that the maximum measured output voltage of an NG optimized with pretreatments on the as-grown ZnO nanowire films reaches 20 V and the output current exceeds 6 μA, which corresponds to a power density of 0.2 W cm−3. The NG is also demonstrated to replace a battery for driving a electronic watch.
