Spectra Flex Sensor 2.2 Inch Bend Sensor for Hand Gesture & Motion Detection – Flexible Resistive Sensor Module
The Spectra Flex Sensor 2.2 Inch Bend Sensor is a high-sensitivity, flexible resistive sensor designed for precise bend and motion detection in wearable electronics, robotics, and human–machine interaction systems. Engineered for reliability and smooth performance, it changes resistance based on the degree of flex, making it ideal for capturing finger, hand, or joint movements in real time.
Built with durable yet ultra-thin flexible material, this sensor easily integrates into gloves, prosthetics, robotic arms, and gesture-controlled devices. Its 2.2-inch active sensing length provides accurate curvature measurement while maintaining excellent responsiveness and long operational life under repeated bending cycles.
Features
- 2.2-inch flexible sensing area for accurate bend detection
- Resistive output varies smoothly with curvature changes
- Ideal for hand gesture recognition and motion tracking systems
- Lightweight, thin, and highly flexible design for wearable applications
- Easy integration with microcontrollers like Arduino, ESP32, and Raspberry Pi
- Suitable for robotics, gaming controllers, prosthetics, and interactive devices
