Power Generation Structure and Energy Harvesting Device

Abstract

A power generation structure and energy collection device. The power generation structure includes: an electrode unit group, including a plurality of electrode units arranged at intervals, and the materials on the opposite surfaces of adjacent electrode units are located in different triboelectric sequences; a push rod, Located at the interval between two adjacent electrode units or close to a certain electrode unit; wherein, under the action of an external force, the relative position of the push rod and the electrode unit group moves, and the path of the relative position movement is related to the distribution of the electrode unit group Consistent, so that the push rod pushes and slides through several electrode units in the electrode unit group in turn, and the electrode units that the push rod pushes and slides in turn form a plurality of contact-separated power generation units with adjacent electrode units, and each power generation unit is in accordance with The sequence in which the rods are pushed into contact produces multiple electrical outputs with successive phase sequences. While ensuring the output performance, the service life of the power generation structure is prolonged and the reliability is improved.

technical field [0001] The disclosure belongs to the technical field of nanometer power generation, and relates to a power generation structure and an energy collection device. Background technique [0002] As a revolutionary technology for converting low-frequency mechanical energy into electrical energy, triboelectric nanogenerator (TENG) has aroused great interest of researchers due to its advantages of high peak power, light weight, simple design, environmental protection, and diverse material selection. These advantages make it a promising distributed energy supplementary technology to directly supplement the energy consumption of supercapacitors / batteries to drive small electronic devices. [0003] "Peak ratio" is defined as the ratio of the current peak value to the equivalent current.

AI Technical Summary

Problems solved by technology

The effective current of the typical short pulse output of TENG is much lower than the peak value, and there is a disadvantage of high output peak ratio. Some studies have solved the problem of partial power loss by connecting all friction nanogenerator units in parallel and then outputting them through rectification. , but the TENG output peak ratio of this circuit connection is usually between 6-10, which is still very high

The TENG structure based on the rotation-sliding mode proposed in some studies effectively reduces the peak ratio, but the continuous friction between the electrode and the dielectric layer will generate a lot of heat, causing damage to the friction material, and the working life needs to be improved, which limits this structure. Working life and commercialization of TENG

[0004] Therefore, solving the shortcomings of power loss when paralleling TENG, high TENG output peak ratio, and short life of the rotating structure at the same time is a technical problem that TENG needs to solve urgently as a supplement to distributed energy.
