Its flexible substrate changes resistance linearly when bent, making it ideal for wearable electronics, robotics, and interactive installations. With a compact 2.2-inch sensing area, it integrates easily into gloves and controllers for real-time motion capture.\u003c\/p\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensing Length\u003c\/td\u003e\n\u003ctd\u003e2.2 inches (56 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Resistance (Flat)\u003c\/td\u003e\n\u003ctd\u003e10K ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResistance at 90° Bend\u003c\/td\u003e\n\u003ctd\u003e~20K ohms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Rating\u003c\/td\u003e\n\u003ctd\u003e0.5 Watts continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum Bend Radius\u003c\/td\u003e\n\u003ctd\u003e0.5 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-35°C to +80°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/esp32-gesture-glove-kit-for-arom-physiotherapy-exercises\"\u003eHand gesture recognition glove for controlling devices\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/robotic-finger-that-bends-with-your-hand-arduino-kit\"\u003eRobotic hand control with real-time finger tracking\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003eInteractive art installations responding to bending motions\u003c\/li\u003e\n\u003cli\u003eGaming controller with motion-sensing triggers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCompatibility\u003c\/h2\u003e\u003cp\u003eThis flex sensor operates at 5V logic levels and interfaces directly with any analog-capable microcontroller. Common pairings include Arduino Uno, Mega, Nano, ESP8266, and Raspberry Pi Pico. It works with both 3.3V and 5V systems when using an appropriate voltage divider with a fixed resistor equal to the sensor's nominal resistance.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect one end of the sensor to VCC (5V or 3.3V) and the other end to a fixed 10K resistor to ground. The junction point goes to an analog input pin. No pull-up or pull-down resistor needed; the fixed resistor forms the divider. Avoid excessive bending beyond the minimum radius to prevent damage.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
