US 2022/0316439 A1 · Hybrid Triboelectric And Electromagnetic Generator

Abstract

A power generator or sensor apparatus is provided. Another aspect employs a hybrid triboelectric and electromagnetic generator. In still another aspect, a power generator is used for water wave energy harvesting. A further aspect provides a power generator including an outer housing with an electrical conductor on an exterior thereof, radial overlapping electrodes located within the housing with a dielectric layer between the electrodes, a plate linearly moveable within the housing, at least one magnet affixed to the plate, and at least one spring biasing the plate within the housing. Moreover, an aspect of the present power generator includes a modularized connection configuration to linearly secure together multiples of the housing.

Dependent claims

A power generator apparatus comprising:

(a) an enclosed housing;
(b) at least one stationary and annular electrode affixed to the housing;
(c) at least one movable and annular electrode concentrically located within the stationary electrode;
(d) a plate transversely extending within the housing and being located within a hollow central area of the movable electrode;
(e) at least one spring biasing the plate away from ends of the housing;
(f) at least one magnet attached to and moveable with the plate;
and
(g) the plate being linearly movable in response to movement of the housing which causes the movable electrode to move along a longitudinal direction, which generates both triboelectric and electromagnetic energy.

A power generator apparatus comprising:

(a) a housing being elongated in a longitudinal direction between end walls thereof;
(b) multiple, longitudinally spaced apart and annular first electrodes affixed to the housing;
(c) multiple, longitudinally spaced apart and movable second electrodes located within a hollow space internal to the first electrodes;
(d) multiple magnets being moveable within the hollow space, the magnets being laterally spaced apart from each other;
(e) at least one spring biasing the magnets relative to the end walls of the housing;
