The 2.2" Flex / Bend Sensor is a compact electronic component that detects bending and movement. Its electrical resistance changes as the strip is flexed, so a microcontroller can read how much it is curved and turn that into a real input. The short 2.2-inch length makes it easy to mount on small surfaces, fingers, joints, or moving parts. It suits hobbyists, students, makers, and anyone building robotics, wearables, or interactive automation projects.
Key features
- Compact 2.2" length that fits tight spaces and small builds.
- Variable resistance output that responds to bending and flexing.
- Simple two-pin connection that works with common microcontrollers.
- Lightweight and thin, easy to attach to gloves, joints, or panels.
- Reusable across many learning and prototype projects.
Typical uses
- Robotic hands and gesture-controlled gloves.
- Wearable and motion-sensing prototypes.
- Position or angle feedback in DIY automation.
- School, university, and maker electronics experiments.
How to choose / tips
- Pick the short 2.2" size for fingers and small moving parts; longer sensors suit larger bends.
- Use it as a variable resistor in a simple voltage-divider circuit for clean readings.
- Avoid sharp creases or folding past its natural arc to keep it working longer.
