Thin film pressure sensors have a wide range of application fields

Thin film pressure sensorIt is a common and important sensor widely used in various industrial and scientific fields. The principle of a thin film pressure sensor is to measure pressure changes by utilizing the elastic deformation of the thin film material. This article will provide a detailed introduction to the working principle, application areas, and future development trends of thin film pressure sensors.

The working principle of thin film pressure sensors is very simple but also very effective. It is composed of two layers of thin film material, usually metal or plastic. There is an insulating material sandwiched between these two thin films. When external forces act on the surface of the sensor, the distance between the upper and lower thin films will undergo a slight change, resulting in a change in the resistance value. By measuring the change in resistance value, we can determine the magnitude of external pressure. The advantage of this working principle is its simplicity, reliability, and relatively low cost.
