Abstract

The invention mainly relates to a bionic micro-flow sensor. The bionic micro-flow sensor comprises a bionic pressure sensing device and a circuit device. The bionic pressure sensing device comprises ashell and a bionic pressure sensor arranged on the shell. The bionic pressure sensor is in circuit connection with the circuit device. The bionic pressure sensor is a bionic crack sensor taking a scorpion body surface seam sensor as a prototype. A bionic pressure sensing element obtained by utilizing the stress mechanism of a scorpion body surface seam sensor is applied to the bionic micro-flow sensor provided by the invention, so that the sensitivity coefficient and accuracy of the bionic micro-flow sensor in fluid data detection are greatly improved.

Description

technical field [0001] The invention relates to the technical field of flow sensing components, in particular to a bionic micro flow sensor and a detection method thereof. Background technique [0002] The performance of flow sensor is of great significance to fluid measurement. For example, hydrological environment monitoring needs to obtain the flow of rivers; in order to maintain the normal pressure in the spacecraft cabin, it is necessary to perform leak detection on the cabin and accurately detect the leakage rate and flow rate, which is especially important for long-term manned spacecraft; In the chemical industry, it is required to precisely control the injection of gas flow rate to ensure the stability of process quality and product performance. [0003] At present, the main gas flow detection methods include: mechanical gas flow detection, hot-wire hot film gas flow detection (HWA), ultrasonic and laser Doppler flow velocity and flow detection methods, etc. Howeve...
