description With rise in trend in nanotechnology there’s interest in finding method to convert mechanical to electrical energy with a miniaturized mechanism that can self-sustain as a standalone system rather than powered by a power supply. Although there are a few methods of converting mechanical energy to electrical energy such as electromagnetic induction, piezoelectric effect and electrostatic induction methods. Unfortunately, electric generators based on electromagnetic induction are very hard to be downsized to micro or submicron scales.
