A force-sensitive resistor (FSR) is a material which changes its resistance when a force or pressure is applied. The conductive film is an example of such force resistance material. 
In other words, force-sensitive resistor it is a sensor that allows you to detect physical pressure, squeezing and weight. The FSR 402 is a single-zone Force Sensing Resistor that optimized to use in humans touched electronic devices control. FSRs are two-wired devices with resistance. It made of the robust polymer thick film (PTF) sensors that exhibit a decrease in resistance with an increase in applied force to the surface of the sensor. Force sensing resistors include a piezoresistive sensing technology. 
It means they are passive elements that function as a variable resistor in an electrical circuit. There are two major operation principles in Force-sensing resistors: percolation and quantum tunneling. 
Although both phenomena actually occur simultaneously in the conductive polymer, one phenomenon dominates over the other depending on particle concentration. 
Force-sensing resistors are commonly used to create pressure-sensing "buttons" and have applications in many fields, including musical instruments, car occupancy sensors, artificial limbs, Foot pronation systems and portable electronics. They are also used in Mixed or Augmented Reality systems as well as to enhance mobile interaction.
