This is the Flexible Sensor/ Flex Sensor. This sensor works on resistance across the sensor when the sensor bend the resistance of the sensor increase the same characteristics on potentiometer / variable resistors. This sensor works on 5v it read 1023 at 9v it read on 0. As you can see the diagram below it has hook a 220 Ohms resistor from the ground this is a voltage divider that divides the 5v between the sensor and the resistor and hook up to your microcontrollers/SBC. The flex sensor is mostly used on Angle displacement measurement, robotics, gaming and virtual motion, medical devices, computer and peripherals, musical instruments & physical therapy.
