A rotary triboelectric nanogenerator with gravitational potential energy storage function

Abstract

The invention discloses a rotary triboelectric nanogenerator with gravitational potential energy storage function, comprising an outer cylinder, an inner cylinder, a central shaft, a first one-way bearing, a second one-way bearing, an electrode array, flexible blades, A sheet-like thin film array, a first mass block, and a second mass block, the sheet-like thin film array includes several alternately arranged first friction units and second friction units; all electrode units corresponding to the first friction units are connected in series to form a first friction unit. Electrodes, all the electrode units corresponding to the second friction unit are connected in series to form the second electrode; during the rotation of the inner cylinder relative to the outer cylinder, the friction between the flexible blade and the sheet-like film array produces charge transfer, and at the same time the sheet-like film array and the electrode Electrostatic induction occurs between the arrays, thereby outputting an electrical signal to an external circuit through the first electrode and the second electrode. The invention can first convert the external vibration energy into gravitational potential energy, and then convert the gravitational potential energy into electrical energy, thereby improving the size and stability of the output current.

Description

technical field [0001] The invention belongs to the technical field of generators, and in particular relates to a rotary friction nanogenerator with the function of gravitational potential energy storage. Background technique [0002] Wireless sensor network is a distributed sensor network composed of a large number of wireless sensor network nodes that can sense and monitor the outside world. The information of the object has huge application value and potential application prospects in the fields of military, industry, medical treatment, environmental monitoring, traffic management, emergency rescue and disaster relief. With the in-depth application of wireless sensor networks, under some complex conditions of use, such as sensor nodes need to be embedded in bridges, buildings, mechanical equipment, or need to be placed in dangerous areas filled with toxic and harmful substances. Staff cannot reach these locations, and once placed, sensor nodes cannot be re-battered. The...

In addition, waves with smaller amplitudes cannot make triboelectric nanogenerators have higher output currents

However, the stability of the current is an important indicator of the output performance of the triboelectric nanogenerator. The unstable output cannot drive the electronic modules to work normally, and even damage the precise electronic equipment.
