摘要: Generating electrical power from low frequency vibration to portable devices is a challenge that potentially can be met by nonresonant electrostatic energy harvesters. We propose generator employing conductive droplet sliding on microfabricated electret film which sputtered onto an interdigital electrode and charged already during deposition. Droplet motion causes capacitance variation used generate electric power. A prototype of the fluidic harvester demonstrated peak output at 0.18 µW with single having diameter 1.2 mm 2 -µm thick film.
