Flex Sensor 4.5″ Bend Sensor for Hand Gesture Recognition is a simple resistive sensor that is 4.5″ in length yet a powerful sensor to sense flexibility. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (the text on the inside of the bend). The connector is 0.1″ spaced and breadboard friendly. The flex sensor is a bend detecting sensor that has got numerous applications in robotics, medical and haptic technology. The resistance of these sensors changes in accordance with the bend, which can be measured using any microcontroller.
