Measuring Bend Angle using a Flex Sensor Circuit

Last updated on 24 November 2025 by Admin-Lavi Leave a Comment

Flex sensor is a small strip that changes resistance when we bend it. When straight, resistance is low. When bent, resistance becomes high. Many projects use this sensor. It is used in robots, gloves, gaming, medical tools and wearables. Sensor works simple with more bend gives more resistance. Flex Sensor Output Voltage Comparison Graph: Circuit […]
