Flex Sensor 2.2 inch

Flex Sensor is a versatile and lightweight resistive sensor designed to detect bending, flexing, and motion with high accuracy. Widely used in robotics, wearable electronics, gaming interfaces, and medical devices, flex sensors convert physical deformation into measurable electrical signals. Whether you are a student, researcher, hobbyist, or professional engineer, this sensor provides a reliable and cost-effective solution for capturing real-world movement in digital systems.

Built using a flexible substrate coated with conductive ink, the flex sensor changes its resistance when bent. As the bending angle increases, the resistance rises proportionally, allowing microcontrollers like Arduino, Raspberry Pi, ESP32, and STM32 to easily interpret motion and position data. Its thin profile, low power consumption, and durability make it ideal for embedded systems and smart sensing applications.

⚙️ How It Works

The flex sensor functions as a variable resistor. When the sensor is straight, it exhibits low resistance. As it bends, conductive particles inside the sensor spread apart, increasing resistance proportionally to the bend angle. By placing the sensor in a voltage divider circuit and reading the output using an analog pin, users can easily convert mechanical motion into digital data for real-time monitoring and control applications.
