Flex Sensor 2.2 inch
Couldn't load pickup availability
The 2.2-inch Flex Sensors are commonly used in Robotic Gloves and other Robotic Control applications. It can be used to analyse how much 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 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.

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