Abstract

The invention relates to an external charge excited friction generator (ECE-TENG), including a primary TENG, characterized in that: the generator further comprises an upper substrate, A low substrate,an excitation TENG and a charge excitation system, on the excitation TENG and the main TENG, A low electrode is mounted on each of that upper electrode, on the lower substrate, the charge excitationsystem comprises a voltage doubling rectifying circuit and a voltage stabilizing circuit, The output voltage of the voltage doubling rectifying circuit is higher than the input voltage, the input endof the voltage doubling rectifying circuit is respectively connected to the electrode for exciting an TENG electrode, the output end of the voltage doubling rectifying circuit is respectively connected to the two electrodes of a main TENG, and the voltage regulating circuit is connected to the output end of the voltage doubling circuit to stabilize and control exciting voltage. The external chargeexcitation friction generator of the invention is novel and reasonable in design, simple in manufacture and low in cost.

Description

technical field [0001] The invention relates to the field of friction nano power generation, in particular to an external charge excited friction generator (ECE-TENG). Background technique [0002] Triboelectric nanogenerators (TENGs) based on triboelectric effects are widely used to harvest environmental mechanical energy such as vibration, sliding, rotation, wind energy, water energy, and even sound to meet the energy demand of society. [0003] The practical application and commercialization of TENG are largely restricted by its current low output power, and the output power of triboelectric nanogenerators is quadratically proportional to the charge density of its tribosurface. Therefore, for traditional triboelectric nanogenerators, A lot of work, such as: material selection, contact improvement, material surface modification, ion implantation and environmental control, etc., are all devoted to improving the tribosurface charge density of TENG in order to obtain greater ...
