The 4.5" Long Flex / Bend Sensor is a thin, lightweight strip whose electrical resistance changes as it is bent. It turns physical movement and curvature into a readable signal, making it a favourite component for makers, students, and engineers building interactive electronics. The longer 4.5-inch body gives you more surface to detect motion along a finger, joint, or moving part, which suits gloves, robotics, and motion-tracking builds.
Key features
- Long 4.5-inch sensing length for capturing larger bend movements
- Slim, flexible profile that fits gloves, hinges, and curved surfaces
- Resistance changes smoothly with the degree of bend for analog reading
- Works easily with Arduino, microcontrollers, and common breadboards
- Lightweight and easy to mount in compact DIY assemblies
Typical uses
- Smart gloves and gesture-controlled projects
- Robotic fingers, arms, and joint movement detection
- Wearable electronics and motion-tracking prototypes
- Arduino and student STEM/electronics experiments
How to choose / tips
- Pick the 4.5-inch length when you need to read longer or wider bends; shorter sensors suit single-finger joints.
- Pair it with a simple resistor to build a voltage divider for clean analog readings.
- Avoid creasing or over-folding the strip; gentle, repeated bending gives the most reliable life.
