Two-Capacitor Electric Microgenerators

August 12, 2020 Engineering 0

All modes of operation of a two-capacitor generator based on overflow of the charge accumulated in
capacitors through the load resistance between two capacitors with antiphase modulated
capacitances by means of in-plane or out-of-plane shift of the electrode plates under action of a
mechanical force are analyzed paying the especial attention to fabrication of the generators with small
sizes. Numerical solutions for all the modes are obtained, and they are found to be universal.
Analytical estimates of the maximum power of the generator as a function of the capacitances
modulation factor are derived. Experimental investigations of a two-capacitor rotational electric
generator show that its characteristics are consistent with the analysis performed and that this
analysis can be used to describe all specific features of operation of particular generators.
Applications of the devices in micro-design for feeding the remote sensors are discussed.
