Capacitive flexible pressure sensor

Capacitive flexible pressure sensors usually use a metal-plated film or metal film as the electrode of the capacitor. It can convert the changes in external pressure that it feels into an electrical signal, which mainly generates capacitance by sensing the external pressure, and obtains the corresponding electrical signal by changing the capacitance. The working principle of the capacitive flexible pressure sensor is: when a certain pressure is given from the outside, the metal-plated or metal film will feel the pressure and deform, and the capacitance between the film and the fixed electrode will change accordingly, thus outputting The corresponding electrical signal. This kind of flexible pressure sensor has a high response speed and dynamic range, and a high sensitivity to force changes, so it can accurately detect tiny static forces with low energy consumption.
