2PCS Thin Film Pressure Sensor 9 Zone Multipoint Array Flexible High Sensitivity Force Sensitive Resistor auspowers_batchthree They come in a 122PCS Thin Film Pressure Sensor 9 Zone Multipoint Array Flexible High Sensitivity Force Sensitive Resistor Product Features 9 Independent Sensing Areas: The thin film touch sensor features 9 distinct sensing areas, each of which exhibits changes in output resistor in response to external pressure variations. When pressure is around 1g, the sensor triggers with a resistor value below 200 K. As pressure increases, the resistor decreases accordingly. At
