Problems solved by technology

[0002] At present, some research results have been achieved in sensors based on the principles of sound waves, electrostatic capacitance, thermal effects, microwaves, etc. for the detection of flow velocity and composition analysis of microfluids. However, most of the sensors have complex working principles and manufacturing processes, low integration, and require an external power supply. Power supply, once there is a problem with the external power supply, the detection of the parameters of the fluid cannot be realized, which has certain limitations and low applicability

Abstract

The invention relates to the technical field of friction power generation, and discloses a fluid friction nanometer sensor, a sensing network and a fluid detection system. The fluid friction nanometer sensor comprises a first part arranged on the inner wall of a cavity, wherein the first part comprises a first frictional layer, on which friction charges representing fluid parameter is generated when fluid in the cavity flows by the surface of the first frictional layer, and a first electrode layer which is attached to the first frictional layer and used to generate sensing charges on corresponding position thereof when friction charges are generated on the first frictional layer. The fluid friction nanometer sensor can realize detection of fluid parameters without an external power.
