This is a four channel buffer circuit for the Spectra Symbol flex sensors. They are available through Sparkfun and other distributors as well as through us (here). The circuit also provides a simple low Q Sallen-Key low pass filter. This should limit noise and the op amp provides for a low impedance input into an ADC for reading the flex sensor value. The circuit is designed to provide a full 0-3.3V swing for the common resistance range of the flex sensors.
Fyber Labs tracks movement and flex of wearables through a variety of sensors, including flex sensors. The common application is to track body joint movement such as fingers. We have also utilize two sensors, one on the top of a flexible board to track X board flex, another on the bottom to track Y. This allows us to understand body response and stress to our board and its positioning.
This is a ready to go, tiny breakout for buffering flex sensors. Just connect the flex sensor to input and ground and send the output to the ADC.
Designed, fabricated, and shipped from the US.
