The 2.2-inch Flex Sensor is a bend-sensitive resistor that changes its resistance based on the degree of bending. It is commonly used in robotics, prosthetics, gaming controllers, and gesture recognition systems. The sensor is thin and flexible, making it suitable for integration into gloves, smart wearables, and human-motion tracking applications. As the sensor bends, its resistance increases, allowing microcontrollers to interpret the amount of flex. It has a long lifespan and is highly durable. The flex sensor can be used in smart prosthetics, hand motion tracking, and interactive gaming applications.
