Abstract :
This paper reports about multistage electrostatic energy harvesters that are based on mechanically-variable capacitors and do not require startup batteries. Analytic models of single-stage and multistage energy harvesters are presented to reveal the design trade-offs useful for increasing harvested power and conversion efficiency. Simulation results using real switching elements are in good agreement with the models.
