When pressure is applied to the sensing area, the resistance of the sensor changes. Force sensing resistors not only can give you resultant pressures but could also tell you specifically where on its surface a force is felt. What is a Force Sensitive Resistor? Force sensing resistors can be designed as single-point force sensors, or in a matrix array form, allowing the user to capture pressure distribution over a given area. On the other hand, if little Many force measurement applications call for an FSR (force sensitive resistor) that is ultra-thin, accurate, cost-effective, and customizable. This is a force sensitive resistor with a square, 1.75x1.5", sensing area. FSRs are sensors that allow you to detect physical pressure, squeezing and weight. When there is no pressure, the sensor looks like an infinite resistor (open circuit), as the pressure increases, the resistance goes down.
