LGSWITCH Film Potentiometer Sensor Applications

Product  Introduction

The Film Potentiometer Sensor responds to a different resistance value by the force applied to the sensing area. The Sensor with ultra-thin, flexible, durable, wide range of pressure detection and easy integration and other features to help people interact with the device more smoothly, help innovative smart products to save costs and reduce time to market.


The Potentiometer Sensor consists of a polyester film with excellent mechanical properties, a highly conductive material and a nanoscale pressure sensitive material. The top layer is a flexible film and a composite pressure layer on the top. The bottom layer is a flexible film and a composite conductive wire. Both through the double-sided adhesive paste to isolate the sensing area. When the induction zone is compressed, the lines that are disconnected from each other through the top layer of the pressure-sensitive layer conduction, the port resistance output value changes with the pressure.
