Pololu Force-Sensing Resistor: 1.5" Square

Key Features:

• 1.5" square - Flexible, light ( 1.2 g), and extremely thin ( 0.02 ″ )
• Masked adhesive backing for easy mounting
• Compatible with most solderless breadboards and perfboards
• Force accuracy ranges from 5% to 25%

This force-sensing resistor (FSR) from Interlink Electronics is a passive component that acts as a variable resistor, with resistance decreasing in response to increasing applied force, which makes it easy to add a touch interface to your project or create a robot with much more sophisticated tactile senses than are possible with simple lever switches. The polymer thick film (PTF) device is optimized for use in human touch control of electronic devices and can sense an applied force anywhere in the active area ranging from a few dozen grams to a few kilograms ( 0.2 N to 20 N).
