This is a clone version of the Flex Sensor 2.2", commonly available in the local market. Unlike the original Spectra Symbol version, this variant shows only a minimal and abrupt resistance change (typically 1–2 kΩ) between straight and bent positions, which may impact precision in sensitive applications. It is a cost-effective option suitable for basic or non-critical use cases, but we do not recommend it for projects requiring high accuracy or consistent sensor behavior.
Looking for the original? Flex Sensor 2.2" Spectra SymbolA 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.
