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 1.5"×1.5" (38×38 mm) active area, allowing you to create a sensor that is able to detect force or pressure. The polymer thick film (PTF) device is optimized for use in human touch control of electronic devices and can sense an applied force ranging from a few dozen grams to over 10 kg (22 lb).
