Abstract
A generator for harvesting energy from water in motion includes a sheet of a hydrophobic material, having a first side and an opposite second side, that is triboelectrically more negative than water. A first electrode sheet is disposed on the second side of the sheet of a hydrophobic material. A second electrode sheet is disposed on the second side of the sheet of a hydrophobic material and is spaced apart from the first electrode sheet. Movement of the water across the first side induces an electrical potential imbalance between the first electrode sheet and the second electrode sheet.

A generator for harvesting energy from water in motion, comprising:
- (a) a sheet of a hydrophobic material, having a first side and an opposite second side, that is triboelectrically more negative than water;
- (b) a first electrode sheet disposed on the second side of the sheet of a hydrophobic material;
- and
- (c) a second electrode sheet disposed on the second side of the sheet of a hydrophobic material and spaced apart from the first electrode sheet,
- so that movement of the water across the first side induces an electrical potential imbalance between the first electrode sheet and the second electrode sheet.
A generator for harvesting energy from water in motion, comprising:
- (a) a confining frame
- (b) at least one contact mode triboelectric nanogenerator disposed within the confining frame;
- (c) an inertial member disposed within the confining frame, the inertial member having at least one degree of freedom of movement and disposed to be able to impart force on the at least one contact mode triboelectric nanogenerator when the confining frame is moved during wave action, thereby causing the triboelectric generator to generate and electrical current.
