Description

Flex Sensor 2.2" Bend Sensor for Hand Gesture Recognition

The 2.2 inch flex sensor is commonly used in robotic gloves and other robotic control applications. It can be used to analyse how much a material is being bent. This flex sensor is 2.2” long and has two output leads that act like a variable resistor. The resistance between two pins changes 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 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 inch flex sensor Arduino compatible module that can be easily interfaced with boards like 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.

Features:

  • Length: 2.2 inches (5.6 cm)
  • Resistance: Changes as the sensor is bent
  • Operating Voltage: 0-5V DC
  • Power Rating: 0.5 Watts (continuous), 1 Watt (peak)
  • Ideal for flex sensor Arduino projects and bend detection applications

Applications:

  • Angle Displacement Measurement.
  • Bends and Flexes physically with the motion device.
  • Robotics Applications
  • Gaming (Virtual Motion)
  • Can be used in physical therapy

Why Choose Flex Sensor 2.2 inch?

If you're looking for a reliable flex sensor buy option for your DIY electronics or robotics project, this sensor is a great choice for beginners and professionals alike. The 2.2 inch size makes it compact and suitable for wearable tech, robotic fingers, gesture control systems, and health monitoring devices.

It is especially popular in Arduino-based projects where precise bend detection is required, making it a practical flex sensor Arduino solution for prototyping and development.

    Working Principle of the 2.2-inch Flex Sensor

    A flex sensor changes its resistance based on how much it is bent. When the sensor is straight, it has a lower resistance. As the sensor bends, the conductive ink inside stretches, increasing the resistance. This change in resistance can be measured using a microcontroller (like Arduino) to detect the amount of bend or motion.

    • Straight position: Lower resistance (around 10k–30kΩ).
    • Bent position: Higher resistance (can go up to 20k–40kΩ depending on bend angle).
    • The resistance increases smoothly, making it ideal for motion tracking.

    Circuit Connection Example (With Arduino)

    Below is a simple voltage divider setup to read sensor values:

    • Connect one end of the flex sensor to 5V.
    • Connect the other end to A0 (analog pin) and a 47kΩ resistor.
    • Connect the other end of the 47kΩ resistor to GND.

    Arduino Code Snippet

    
int flexPin = A0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int sensorValue = analogRead(flexPin);
  Serial.println(sensorValue);
  delay(100);
}

    Popular Projects Using the Flex Sensor

    • Robotic fingers and hand movement simulation.
    • Gesture-controlled robotic arms.
    • Smart gloves for gaming and VR control.
    • Wearable devices for posture or movement tracking.

    How To

    1. How to interface a Flex Sensor 2.2 with Arduino?

    To interface the flex sensor 2.2 with Arduino, connect it in a voltage divider circuit and feed the signal to an analog pin. This lets you track bending motion for projects like finger tracking or even controlling a small servo.

    2. How does a Flex Sensor work?

    The sensor changes resistance when bent — higher resistance when flexed and lower when straight. This simple principle makes a long flex sensor suitable for wearable electronics, motion tracking, and gesture control.

    3. How to calibrate a Flex Sensor 2.2?

    Calibration involves recording the resistance values in both straight and bent positions using Arduino. Mapping these values in code ensures accurate results, especially if you’re building a glove with flex sensor for gesture recognition.

    4. How to make a flex sensor at home?

    DIY flex sensors can be made with conductive ink or carbon materials, but they are less reliable. A ready-made flex sensor 2.2 offers better durability and consistent readings for Arduino projects.

    5. How to connect a Flex Sensor to Arduino?

    Connect one end of the sensor to 5V and the other through a fixed resistor to ground, then read the voltage at the junction on an Arduino analog pin. This setup is often used in flex sensor Arduino projects like controlling servos or interactive devices.

    FAQ

    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.
