Piezoelectric flexible pressure sensor

Piezoelectric flexible pressure sensors are mainly composed of piezoelectric sensitive materials, such as polyvinylidene fluoride, etc. which use piezoelectric materials to convert pressure to electrical signals. Its working principle is: the higher the piezoelectric coefficient, the higher the energy conversion rate of the piezoelectric sensitive material, and the stronger the electric signal converted. Piezoelectric flexible pressure sensor is a sensor that uses piezoelectric materials to convert pressure to electrical signals. This type of flexible pressure sensor has high sensitivity, accuracy, piezoelectric coefficient, and response speed, so it is widely used as a flexible touch sensor.
