Description
MINIMUM TECH FEATURES:
- Operating Voltage: 0–5V DC
- Flat Resistance: 25KΩ (typical)
- Range of Bend Resistance: 45KΩ – 125KΩ
- Continuous Power Rating: 0.5W
- Peak Power Rating: 1W
- Life Cycle: > 1 million flexes
- Length: 2.2 inches (approx. 55mm active sensing area)
DESCRIPTION:
- The FLEX-2.2-INCH sensor (by Spectra Symbol) is a variable-resistance device that changes its resistance according to the amount of bend or flex applied.
- It provides analog output proportional to the degree of bending — ideal for applications in motion sensing, robotics, gaming, and biomedical devices.
- The flat, lightweight construction allows it to be easily attached to gloves, exoskeletons, or joint measurement setups.
- Offers reliable, repeatable performance with over a million flex cycles, ensuring durability and consistency.
- Output can be easily read using an Arduino, Raspberry Pi, or any microcontroller with an ADC input.
- Commonly used for hand gesture recognition, angle measurement, and robotic motion feedback systems.
