♦ What is Force Sensing Resistor (FSR)? 

    Force sensing resistor or we call force sensor, can be defined as a special type of resistor which exhibits a decrease in resistance with an increase in the force applied to the active sensing surface. The force sensing resistor is generally supplied as a polymer sheet or ink which is applied as screen printing. Both the electrically conducting and non-conducting particles are present on this sensing film. If force is applied to a surface of sensing film, then the particles touches the conducting electrodes and thus resistance of the film changes. There are several resistive based sensors but force sensing resistors operate satisfactorily in difficult environments and also requires a simple interface compared to other resistive based sensors. 
    Even though there are various types of force sensors, the force sensing resistors are having several advantages such as thin size (less than 0.5mm), very low cost and also good shock resistance. The only disadvantage of FSR sensors is low precision, there will be approximately 10% or more difference in measurement results. So it can't be used as weighing equipment. It acts as a reaction of force rather than as an accurate reading of pressure. 

♦Applications of Force Sensing Resistor

     There are numerous applications for force sensing resistors in various fields such as motion analysis systems, automobiles like car sensors, resistive touch-pads, musical instruments, Medical bed, Measurement of bite force of teeth, die pressure measurement,and so on. It may be used wherever pressure measurements and data collection are required
