Built with advanced sensing technology, this Flex Sensor provides precise and repeatable measurements, even in harsh environments. Its flexible construction allows it to bend and flex without sacrificing accuracy, making it ideal for use in applications such as robotics, wearables, and medical devices.
Thanks to its durable construction, this sensor is built to withstand even the most demanding applications. It features a rugged outer casing that protects the sensing element from damage, as well as an industry-standard connector for easy integration with a wide range of systems.
Installation of the Flex Sensor is a breeze, with no special tools or expertise required. Simply attach the sensor to your system using the provided mounting hardware, and connect it to your control or measurement system using the standard connector.
Whether you're building a wearable fitness tracker, a robotic gripper, or a medical device, our Flex Sensor is the perfect choice for accurate and reliable measurement of bending and flexing. With its advanced sensing technology, rugged construction, and easy installation, you can trust it to deliver the precise measurements your application needs.
A simple flex sensor 2.2" in length. As the sensor is flexed, the resistance across the sensor increases. Patented technology by Spectra Symbol - they claim these sensors were used in the original Nintendo Power Glove. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Connector is 0.1" spaced and bread board friendly.
Length: 2.2"

Flex Sensor (2.2") Tutorial: How It Works, Voltage Divider Wiring, Arduino/ESP32 Reading, Calibration to Bend Angle, Filtering, and Real Projects
This tutorial is a detailed, practical guide to using the Flex Sensor (2.2") (Leobot Product #4148) to measure bending for robotics, wearables, gesture control, and mechanical feedback. You’ll learn what a flex sensor actually outputs (it’s a variable resistor), how to wire it safely with a voltage divider, how to read it accurately with Arduino/ESP32 ADCs, how to calibrate it to a bend angle (or “bend amount”), and how to build robust code with smoothing, deadbands, and fault detection.
