Abstract

The invention discloses a DC nano generator and a sensor capable of collecting mechanical energy and heat energy simultaneously. The DC nanogenerator capable of collecting both mechanical energy and thermal energy includes a body, a rotor part and a stator part; the inside of the body has an accommodation space; the rotor part is arranged in the accommodation space, and the rotor part includes a friction medium layer; the stator part is arranged in the accommodation space and Set opposite to the rotor part, the stator part includes a friction electrode and a charge collection electrode, wherein the friction electrode is set facing the friction medium layer, when the stator part and the rotor part move relative to each other, the friction electrode and the friction medium layer can triboelectrically electrify, and the charge collection electrode faces The friction medium layer is arranged at a predetermined distance from the friction medium layer, so that an electric field is formed between the charge collecting electrodes and the friction medium layer when the stator part and the rotor part move relative to each other. The DC nanogenerator capable of simultaneously collecting mechanical energy and heat energy of the present invention has a high conversion rate for mechanical energy and can simultaneously collect heat energy.

Description

technical field [0001] The invention relates to the technical field of energy collection, in particular to a direct current 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, the existing AC triboelectric nanogenerators 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. The final energy output of the generator will not exceed the input mechanical energy, and the overall energy conversion rate is low.
