Optimal Capacitive Load Matching of Micro Electret Power Generators


This paper presents a model of micro-electret power generators. This model uses two capacitors with fixed charge density and variable area to model the actual micro electret power generator. Simulations of power output with capacitive loads and resistive loads are presented. The power output decreases as the load capacitance increases while it increases as the resistive load increases. To verify the model and simulation results, power output generation experiments are performed and the results confirm the simulation. To collect useful energy from the power generator, a small capacitive load, rather than a resistive load, is required.
