  • A simple flex sensor 2.2" in length. 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 (text on the inside of bend).
  • Connector is 0.1" spaced and bread board friendly.
  • It comes in the form of a thin strip measuring 7.3 cm long and 6.3 mm wide.
  • It has an operating  voltage range of 0 to 5V DC. While the Power rating is 0.5Watt (continuous), 1 Watt (peak).

Flex Sensor 2.2″ Bend Sensor for Hand Gesture Recognition

The 2.2-inch Flex Sensors are commonly used in Robotic Gloves and other Robotic Control applications. It can be used to analyze how much material is being bent. This flex sensor is 2.2” long and has two output leads that act like a variable resistor. That is the resistance between two pins change based on how much the sensor is bent.  It is commonly used along with another resistor to build a voltage divider circuit and then obtain a variable voltage based on the change in resistance of the sensor.

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.

This is a simple 2.2" long flex sensor that can be used/interfaced with an Arduino. 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 (text on inside of the bend). The connector is 0.1" spaced and breadboard friendly. 

Note: Please refrain from flexing or straining this sensor at the base. The usable range of the sensor can be flexed without a problem, but care should be taken to minimize flexing outside of the usable range. For best results, securely mount the base and bottom portion and only allow the actual flex sensor to flex.

    1. What does a flex sensor do?

    A flex sensor, also known as a bend sensor, is a sensor that detects the amount of deflection or bending. The sensor typically adheres to the surface, and the resistance of the sensor element is varied by bending the surface.

    2. What is the range of a flex sensor?

    The Flex Sensor is a one-of-a-kind component that alters resistance when bent. The nominal resistance of an unflexed sensor is 10,000 ohms (10 K). The resistance gradually increases as the flex sensor is bent. When the sensor is bent at 90 degrees, the resistance ranges from 30 to 40 K ohms.

    3. Which devices uses flex sensor?

    Flex sensors are widely used in a variety of technological products, including automotive and industrial controls, computer peripherals, joysticks, and measuring instruments. These are also found in fitness products, musical instruments, and modern vehicle assistive technology systems.

    4. What is a flex sensor, and how does it work?

    A flex sensor, also known as a bend sensor, detects the amount of bending or deflection. It typically adheres to a surface, and its resistance varies as the surface is bent.

    5. How can I interface a flex sensor with an Arduino?

    You can interface a flex sensor with an Arduino by connecting it to the analog input pins. Typically, it's used along with another resistor to form a voltage divider circuit, which then provides a variable voltage based on the sensor's resistance change.

    6. Can a flex sensor detect both bending and stretching?

    Yes, a flex sensor can detect both bending and stretching. Its sensitivity allows it to accurately detect changes in bending and stretching, providing precise feedback on movement.

    7. What are the applications of flex sensors?

    Flex sensors have various applications including angle displacement measurement, robotics, gaming (virtual motion), physical therapy, and hand gesture recognition systems.
