The Bend Labs Digital Flex Sensors are an innovative solution for measuring motion, providing a unique alternative to existing sensor technologies for measuring a highly accurate and drift-free angular displacement in a soft form factor while maintaining extremely low power consumption. Constructed using highly durable, medical grade silicone elastomers, this is a two axis bidirectional sensor which measures two angles in orthogonal planes for 3D orientation. Where previous flex sensors required analog-to-digital conversion and had delicate connection points, this digital flex sensor has a built-in microcontroller with an easy to use I2C interface. Its low-power, integrated analog front end provides angular displacement data in degrees and includes onboard calibration.
