Triboelectrification is an effect that is known to each and every one probably ever since the ancient Greek time, but it is usually taken as a negative effect and is avoided in many technologies. We have recently invented a triboelectric nanogenerator (TENG) that is used to convert mechanical energy into electricity by a conjunction of triboelectrification and electrostatic induction. This presentation will focus on the integration of a TENG with an energy storage device for building a self-powered power pack. The density of the energy storage unit may not be the highest, but it is being charged continuously so that the energy will not be drained out. This is a new approach toward sustainable operation of small electronic devices.
