COILED AND TWISTED NANOFIBER YARNS FOR ELECTROCHEMICALLY HARVESTING ELECTRICAL ENERGY FROM MECHANICAL DEFORMATION

Publication No.: US2020208614A1 02/07/2020

Yarn energy harvesters containing conducing nanomaterials (such as carbon nanotube (CNT) yarn harvesters) that electrochemically convert tensile or torsional mechanical energy into electrical energy. Stretched coiled yarns can generate 250 W/kg of peak electrical power when cycled up to 24 Hz, and can generate up to 41.2 J/kg of electrical energy per mechanical cycle. Unlike for other harvesters, torsional rotation produces both tensile and torsional energy harvesting and no bias voltage is required, even when electrochemically operating in salt water. Since homochiral and heterochiral coiled harvester yarns provide oppositely directed potential changes when stretched, both contribute to output power in a dual-electrode yarn. These energy harvesters were used in the ocean to harvest wave energy, combined with thermally-driven artificial muscles to convert temperature fluctuations to electrical energy, sewn into textiles for use as self-powered respiration sensors, and used to power a light emitting diode and to charge a storage capacitor.

The upper and lower buoys may be attached to hydraulic cylinder jacks 9, sea water jacks or pneumatic jacks so that the induced movement between the two buoys, due to their differing buoyancy characteristics, is resisted by the cylinder jacks resulting in an increase in pressure. The pressure is employed to drive a hydraulic motor and generator providing electrical power for cable 14 transmission to a grid connector. Compartments 2 contain the machinery for hydraulic pressure to electrical power conversion. Alternatively, the system may be used to desalinate sea water.

Irregular motion of waves creates a challenge to obtain energy efficiently. Heave type devices have been found to have high efficiencies, but they are limited to capturing energy along one or two directions of freedom. A new system and method for obtaining energy from the heaving motion of the waves is presented. It consists of base and heave structures connected through arm devices comprising three degrees of freedom, said arms powered by the motion of the heave structure in the fluid. These arm devices allow capture of wave energy by mechanical, hydraulic, or pneumatic systems.
