This force-sensing resistor (FSR) from Interlink Electronics is a passive component that exhibits a decrease in resistance when there is an increase in the force applied to the 0.58″-diameter (1.5 cm) active area, allowing you to create a sensor that is able to detect force or pressure. With a force sensitivity range of a few grams to a few kilograms, this sensor is optimized for use in human touch control applications.
Jargon buster
Plain-language definitions for the technical terms used above.
- FSR
- FSR usually means full-scale range, the total span between the lowest and highest value a converter can output or measure, so error figures quoted as a percentage of FSR depend on the selected range such as 2.5 V or 5 V. In other contexts FSR can instead mean a force-sensing resistor, a component whose resistance changes with applied pressure, so check which sense is meant.
