Segmentally structured disk triboelectric nanogenerator

摘要

A generator includes a disc shaped first unit, a disc shaped second unit and an axle. The first unit includes a substrate layer, a double complementary electrode layer and an electrification material layer. The electrode layer includes a first electrode member and a second electrode member. The first electrode member includes evenly spaced apart first electrode legs extending inwardly. The second electrode member is complementary in shape to the first electrode member. The legs of the first electrode member and the second electrode member are interleaved with each other and define a continuous gap therebetween. The electrification material includes a first material that is in a first position on the triboelectric series. The second unit defines elongated openings and corresponding elongated leg portions, and includes a second material that is at a second position on a triboelectric series, different than the first position.

主权项

1. A generator, comprising:
(a) a disc shaped first unit including:
(i) a substrate layer;(ii) a double complementary electrode layer affixed to the substrate layer, the electrode layer including a first electrode member and a second electrode member, the first electrode member including an outer ring and a plurality of evenly spaced apart first electrode legs extending inwardly from the outer ring, the second electrode member complementary in shape to the first electrode member and including a first hub and a plurality of evenly spaced apart second electrode legs extending outwardly from the first hub, the first electrode legs interleaved with the second electrode legs so as to define a continuous gap that separates the first electrode member from the second electrode member; and(iii) an electrification material layer, affixed to the double complementary electrode layer, including a first material that is in a first position on the triboelectric series; (b) a disc shaped second unit, defining a plurality of evenly spaced apart elongated openings extending radially outwardly from a second hub of the second unit to an outer ring portion thereby defining a corresponding plurality of evenly spaced apart elongated leg portions extending radially outwardly from the second hub to the ring portion so that each leg portion has a shape and size corresponding to each opening, the second unit including a second material that is at a second position on a triboelectric series, the second position being different than the first position; and (c) an axle coupling the first unit to the second unit so that the first unit is disposed on the second unit so that the second unit is in contact with the electrification material layer and so that the second unit is configured to rotate relative to the first unit.
