Original Kurzfassung:
The concept and suitable technologies leading to an
electrostatic energy harvester based on the motion of an
electrolyte acting as a liquid electrode are presented. It is
designed to exploit the mechanical energy associated with a 90°
rotation by simultaneously changing the area of two antiparallel
capacitors. In order to increase their capacitance, a custom made
dielectric coating with enhanced relative permittivity is
produced. Tests concerning the mobility of the electrolyte are
presented, which can be potentially improved by adding small
amounts of surfactant. Experimental validation shows promising
results for the proposed energy harvester design being especially
suitable for operation at low frequencies.
