Abstract

The invention provides a reverse electrowetting mechanical energy collection device and a mechanical energy collection apparatus. The reverse electrowetting mechanical energy collection device includes: a first electrode substrate; a second electrode substrate which is arranged opposite to the first electrode substrate to form an accommodating cavity; a solid dielectric layer which is arranged onone side, close to the first electrode substrate, of the second electrode substrate; a liquid injection smooth porous surface layer which is arranged on one side, close to the first electrode substrate, of the solid dielectric layer; and conductive fluid, wherein a containing cavity which is filled with the conductive fluid, and the conductive fluid makes contact with the first electrode substrateand the liquid injection smooth porous surface layer. According to the invention, the structural design of the multi-layer composite dielectric layer of the solid dielectric layer and the liquid injection smooth porous surface layer is adopted, and the hydrophobicity and the insulativity of the dielectric layer are separated, so that a material with a relatively high dielectric constant can be selected as the solid dielectric layer, the dielectric structure limitation of a fluoropolymer is broken through, the functional characteristics of the dielectric layer in a reverse electrowetting system are greatly improved, the problem of charge trapping is effectively avoided, and the energy generation efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of reverse electrowetting, in particular to a reverse electrowetting mechanical energy collection device and a mechanical energy collection device. Background technique [0002] Electrowetting on dielectric (EWOD) refers to placing a polar droplet on an electrode coated with a dielectric layer. If a voltage is applied to this system, the droplet will spread, and the contact area with the dielectric layer phenomenon of increase. Reverse electrowetting (reverse electrowetting on dielectric, REWOD) is the reverse process of dielectric wetting. It refers to the fact that after the polar droplet spreads under the action of voltage, if it shrinks due to external force, the contact area with the dielectric layer will be reduced. If it is reduced, a current will be generated in the circuit. In recent years, reverse electrowetting has been proven to be used for mechanical energy harvesting, and the conversion of me...
