    Description

    This is a genuine Flex Sensor 2.2" manufactured by Spectra Symbol. In Bangladesh, many sellers distribute Chinese clones while claiming them to be original. The most significant distinction lies in resistance behavior: the authentic version exhibits a substantially higher and gradual resistance shift (typically 20–40 kΩ) between straight and bent positions. In contrast, the clone version shows only a 1–2 kΩ change, often abruptly. For applications requiring accuracy and consistency, we strongly recommend using the original sensor.

    We also carry the clone version: Flex Sensor 2.2" China


    A simple Flex Sensor 2.2″ – Bend Sensor with a length of 2.2″ which bends and flexes with a physical device. As the sensor is flex, the resistance across the sensor increases. A connector is 0.1″ spaced and breadboard friendly. Applications in – Robotics, Gaming (Virtual Motion), Medical Devices, Computer Peripherals, Musical Instruments, Physical Therapy.

    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.
    Note: The base of the sensor is sensitive to bending and may get damaged. Make sure that you bend only the sensing area.Featured By RoboticsBD.

    Flex Sensor Overview

    Before we get to circuit-building and Arduino-programming, here's a quick rundown of the flex sensor's important electrical characteristics.

    How it Works

    One side of the sensor is printed with a polymer ink that has conductive particles embedded in it. When the sensor is straight, the particles give the ink a resistance of about 30k Ohms. When the sensor is bent away from the ink, the conductive particles move further apart, increasing this resistance (to about 50k-70K Ohms when the sensor is bent to 90°, as in the diagram below).

    Sensor bent

    When the sensor straightens out again, the resistance returns to the original value. By measuring the resistance, you can determine how much the sensor is being bent.

    Sensor straight

    The flex sensor is designed to be flexed in just one direction – away from the ink – as demonstrated in the image below.

    flex-sensor-direction.png
    Flex sensor bend direction (from SpectraSymbol Datasheet).

    Bending the sensor in the other direction will not produce any reliable data, and may damage the sensor. Also take care not to bend the sensor close to the base, as they have a tendency to kink and fail.

    Hardware Assembly

    The sensors have solder tabs that are stapled through a flexible substrate to make contact with the semi-conductive material. Depending on your project application and skill set, there are a few methods of connecting to the sensor. Some assembly may be required to connect to the pins reliably.
