Thin Film Pressure Sensor, Force Sensitive Resistor (FSR), Ultra-Thin Flexible Pressure Sensor Pad, High Accuracy Resistance-Type Force Sensor for Arduino, IoT, Robotics & Smart Devices

Thin film pressure sensors are precision sensing devices that use advanced thin-film technology to convert pressure into electrical signals.

Our ultrathin, flexible film force sensors (FSRs) are designed for a wide range of force and pressure sensing applications, replacing traditional rigid load cells that are either too bulky or too expensive. Their thin and flexible design allows for easy integration into small consumer electronics, curved surfaces, and wearable devices.
