Function: Flexible bend sensor that measures angular displacement by changing resistance when bent, ideal for detecting motion, flex, and pressure in wearable or robotic applications.

Length: 2.2-inch (55mm) active sensing area — compact and responsive for accurate bend detection in small-scale projects.

Operating Principle: Resistance increases linearly as the sensor is bent; flat position offers low resistance, while maximum bend yields high resistance output.

Compatibility: Works seamlessly with Arduino, Raspberry Pi, and other microcontrollers via analog input pins — easily integrated with voltage divider circuits.

Specifications:

• Flat resistance: ~10kΩ

• Bend resistance: Up to ~30–40kΩ (depending on curvature)

• Bend radius: Up to 90° optimal range

• Operating voltage: 3.3V–5V

Construction: High-quality flexible substrate with conductive ink layers, built for durability and consistent response through repeated bends.

Applications: Perfect for gesture recognition, robotic fingers, gaming gloves, prosthetics, posture sensing, and wearable tech projects.

Design: Slim, lightweight, and highly sensitive — provides smooth analog output proportional to the degree of bending, ensuring precise motion tracking.
