Abstract
In this paper, we introduce a microfluidic self-excited energy conversion system inspired by Kelvin’s water dropper but driven by inertia instead of gravity. Two micro water jets are produced by forcing water through two micropores, breaking up into microdroplets which are inductively charged by electrostatic gates. Targets and electrostatic gates are cross-connected in a way similar to Kelvin’s water dropper. To prevent overcharging of the droplets, a voltage divider using inversely connected diodes was introduced in our system to control the charge induction. Maximal 18% energy conversion efficiency was obtained with the diode-gated system.
