Product description
Flex sensor is a resistive bend sensor used to detect bending or flex in one direction. The sensor works by changing its resistance depending on how much it is bent, making it suitable for applications such as gesture control, wearable projects, robotics, interactive installations, and experiments where motion or deformation needs to be measured. This type of sensor became widely known through its use in the Nintendo PowerGlove as an input device.
The sensor is easy to use and can be connected to an analog input on a microcontroller with a pull-up resistor, or used in timing measurements with an RC network. When the sensor is straight, the resistance is about 25 kohm and increases up to around 100 kohm when fully bent. The lower section where the contacts are located is mechanically sensitive and should be strain relieved to avoid damage to the connections.
