Description

technical field [0001] The invention relates to the field of flexible membrane pressure sensor detection equipment, in particular to an airbag type flexible membrane pressure sensor detection system. Background technique [0002] Flexible film pressure sensor refers to a pressure sensor made of flexible functional materials with strong adhesion, bending resistance and high sensitivity printed on flexible and light materials. The sensor is as thin as paper, with good flexibility, ductility, and even It can be bent and folded freely, and its structure is flexible and diverse. It can be arranged arbitrarily according to the requirements of the measurement conditions, and it is very convenient to measure complex measured objects. [0003] When in use, the sensor is pasted on the surface of the object to be measured. When the sensor senses the external pressure, the resistance value of the sensor changes, and the signal conversion circuit can convert the pressure signal generated...

Problems solved by technology

[0005] At present, when testing the performance of flexible thin-film pressure sensors, the sensor parameters are obtained by manually pressurizing and measuring each sensor. When the number of sensors is large, only some sensors can be selected for testing by sampling to judge the performance of the full-page sensor. , low measurement efficiency, poor measurement accuracy and consistency
