Batteryless electrostatic energy harvester and control system

This work shows how an electrostatic energy harvester based on a “doubler of electricity” can be used as energy source for low-power applications, without the need of a battery, and describes a suitable control system for it. The fact that the generator can be made to start from very small initial charge, which can be provided by electrical noise or external interference, is used to eliminate the need of a battery.
