Non-contact friction nanometer generator and preparation method thereof

Abstract

The invention provides a non-contact friction nano-generator suitable for collecting ocean energy and a manufacturing method thereof, and the non-contact friction nano-generator comprises an external spherical shell, an internal bottom plate, an internal hanging plate, a spring, a PEDOT: PSS electrode, a PU film and an FEP film. When the friction nanometer generator works, oscillation starting of the spring is achieved through pushing of waves in water, so that the upper hanging plate and the lower hanging plate are driven to make contact and be separated, and mechanical energy of the spring is converted into electric energy to achieve power generation. Due to the fact that the double-spring structure is adopted, the generator can output a plurality of electric signals under the action of one-time waves, and the service life of the generator is effectively prolonged. Moreover, the generator uses the PEDOT: PSS film as an electrode material, so the generator has certain transparency, and has the potential of being combined with other related devices, such as a solar cell, a sensor and the like.

Description

technical field [0001] The invention belongs to the field of friction nanometer generators, in particular to a non-contact friction nanometer generator for collecting ocean energy and a preparation method thereof. Background technique [0002] The ocean covers an area of ​​about 360 million square kilometers, accounting for about 71% of the total surface area of ​​the earth. It contains huge energy and is one of the best renewable energy sources. At present, human use of ocean energy mainly relies on generators based on the principle of electromagnetic induction. Ocean energy has the characteristics of low energy frequency, high energy peak randomness, complex energy environment, and wide distribution area. The characteristics of energy collection by electromagnetic induction generators are: the frequency of energy collection is high, the collected energy needs to come from a unified movement direction, and large-scale centralized power generation. To sum up, because there...
