Technical Field

[0002] In modern society, with the rapid development of science and technology, the demand for security monitoring and early warning systems is increasing. Especially in vaults, strongrooms, homes, schools and other places, it is particularly important to detect and handle abnormal events in a timely manner. Traditional security monitoring systems mostly rely on video surveillance and manual patrols, but these methods have disadvantages such as high cost, slow response speed, and susceptibility to human factors. In order to solve the above problems, anomaly detection systems based on pressure sensing materials have come into being. Pressure sensing materials, as a device that can detect pressure changes and convert them into measurable signals, have been widely used in various fields. The principle is to sense the changes in resistance, capacitance or other physical quantities generated by the material when it is subjected to pressure, and then output the corresponding electrical signal. This sensor has the advantages of high sensitivity and fast response speed, and is very suitable for use in anomaly detection systems Summary of the Invention
