Sensors&Printed Electronics
Thin film pressure sensors are sensors based on thin film materials, and their main function is to measure the pressure applied by an object on its surface. They are usually composed of a thin film, a base, and a conductive layer, and their working principle is based on the change in resistance of the thin film material when it is subjected to force. In short, thin film pressure sensors are flexible and versatile sensors that are suitable for a variety of different application scenarios, thus providing solutions for pressure measurement and touch detection.
Working Principle The working principle of thin film pressure sensors is based on the change in the electrical potential of thin film materials when they are subjected to force. These sensors are usually composed of a thin film, a conductive layer, and a supporting base. The following is an overview of the basic working principle of thin film pressure sensors:
Application characteristics
Thin film sensors provide information about pressure levels by monitoring the tiny deformation of thin film materials when they are subjected to force, which is converted into changes in resistance. Here are some of the main applications of thin film pressure sensors:
1. Touch sensing: can be used to detect and measure touch and press. This application is common in devices such as touch screens, electronic keyboards, digital buttons, etc.
2. Force measurement: can measure the amount of force applied to the surface of an object. In industrial, manufacturing and laboratory environments, they can be used to monitor the force on machines and equipment and trigger corresponding actions when needed.
3. Medical equipment: widely used in the medical field, such as making wearable devices, bed monitoring systems or other medical devices to measure the pressure distribution, posture and movement of patients.
4. Automotive industry: In automotive manufacturing, thin film pressure sensors are used to monitor the position and weight distribution of passengers on seats to better control the deployment of airbags.
5. Industrial automation: In industrial environments, these sensors can be used to monitor the pressure, force or touch status of equipment to achieve automated control and monitoring of production processes.
6. Robotics: can be used for touch perception of robot hands or fingers, allowing robots to interact with the surrounding environment more sensitively.
