Description

technical field [0001] The invention belongs to the technical field of pressure measurement, in particular to a test system for measuring the distribution of foot pressure. Background technique [0002] With the development of technology, the demand for contact pressure detection is also increasing. Traditional contact pressure detection mostly focuses on single point detection. However, many industries need to measure multiple points at the same time to obtain the distribution of contact pressure. In industry, the detection of surface pressure is a research hotspot in recent years. To detect the pressure distribution on a curved surface, multiple sensing points are usually placed, and the sensing unit is made of rubber filled with conductive particles. When external pressure is applied, the resistance of the conductive rubber changes, which in turn causes a change in voltage drop. By detecting the voltage drop, the magnitude and distribution of the external pressure can...
