1. Product introduction

Flexible thin -film pressure sensor is a flexible thin film sensor that reduces the pressure on the inductive region as the pressure on the induction area.It is composed of a pool film, high -conductive material, and nano -level pressure sensitive material with excellent comprehensive mechanical properties. The top layer is a flexible film and a composite pressure -sensitive layer on it. The bottom layer is a flexible film and a conductive line on it.It is widely used in many occasions such as sleep status monitoring, in bed monitoring, smart running shoes, smart switches, and detection of human compression on medical equipment.

Flexible thin -film pressure sensor Sensor is equivalent to a dual -port variable resistor controlled by pressure control when working. It needs to convert the changing resistance to a voltage signal that can be identified by the processor.The simplest and most commonly used method is the disadvantage of resistance to pressure division, but the method of resistance to pressure separation is disadvantaged, poor adaptability of different models of sensor.To this end, we have developed a signal conversion module based on the computing amplifier. The module has a high signal output linearity, magnifying multiple, and high measurement accuracy. It can adapt to a variety of types of thin film pressure sensors.This module is plug -in and played, simple and convenient, 0 ~ 3.3V voltage signal output, which can be compatible with 5V.3.3V control system.
