Abstract

The invention discloses a direct-current nano-generator capable of simultaneously collecting mechanical energy and heat energy and a sensor. The direct-current nano-generator capable of simultaneouslycollecting mechanical energy and heat energy comprises a generator body, a rotor part and a stator part; an accommodating space is formed in the generator body; the rotor part is arranged in the accommodating space and comprises a friction medium layer; the stator part is arranged in the accommodating space and is opposite to the rotor part; the stator part comprises a friction electrode and a charge collecting electrode; the friction electrode is arranged to face the friction dielectric layer; when the stator part and the rotor part move relative to each other, the friction electrode and thefriction dielectric layer can form triboelectrification, and the charge collection electrode faces the friction dielectric layer and is spaced from the friction dielectric layer by a preset distance,so that an electric field is formed between the charge collection electrode and the friction dielectric layer when the stator part and the rotor part move relative to each other. The direct-current nano-generator capable of collecting mechanical energy and heat energy at the same time is high in mechanical energy conversion rate and capable of collecting heat energy at the same time.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to a DC nanogenerator and a sensor capable of simultaneously collecting mechanical energy and thermal energy. Background technique [0002] The existing AC triboelectric nanogenerator converts the mechanical energy in the environment into electrostatic energy through contact electrification, and then converts the electrostatic energy into electrical energy through electrostatic induction. [0003] However, due to the existence of dielectric breakdown phenomenon, the existing AC friction nanogenerator can only convert part of the electrostatic energy into electrical energy, while the other part of the electrostatic energy is released due to electrostatic breakdown. Therefore, the existing AC friction nanogenerator The final energy output of the generator will not exceed the input mechanical energy, and the overall energy conversion rate is low.
