Custom printed force sensing resistor

A Force Sensing Resistor (FSR) is a thin, flexible sensor that changes resistance when pressure is applied. It uses a piezoresistive layer to detect force levels.

FSR force sensors are widely used across multiple industries. In healthcare, they monitor patient movement in hospital beds; in robotics, they enable tactile feedback in grippers; in wearable tech, they power smart insoles for gait analysis; and in automotive systems, they detect passenger presence in seats. Their low power use, cost-effectiveness, and easy integration make them ideal for pressure-sensitive applications.
