SPS02 thin film pressure sensor is used for real-time recording of pressure. The advantages of low trigger point, sensitive response and high pressure resolution make it suitable for products such as electric toothbrushes, intelligent handwriting recognition, and electronic notebooks.
It is resistive type pressure-sensitive sensor, and the resistance value decreases as the pressure acting on the sensing area increases. The sensor is equivalent to a variable resistor whose resistance value is controlled by pressure. By setting different activation point of the resistance value, it can be used as a multi-level touch function for applications.
Suzhou Huiwen Nanotechnology hold patent for the product. It also can be customized production of sensor size, shape, range and other parameters.
