What Is a Force Sensing Resistor?

The Force Sensing Resistor (FSR) was invented by the founder of Interlink Electronics, which spearheaded the technology’s adoption in a large and diverse range of industries. FSRs are piezoresistive sensors that use two sets of electrically distinct interdigitated fingers printed on a conductor substrate. A thin spacer separates the circuit from a layer of conductive ink. When a force or pressure, whether from a human touch or other source, is applied to the surface of the sensor, the conductive ink creates shunts between the two sets of fingers, completing the circuit and decreasing the device's resistance, which can be measured.

The resulting sensor is thin, flexible, and resilient. Plus, their low cost and easy integration make them a great choice for scalable projects.
