Is there a Bi directional flex sensor (getting back and forth) for a smart plush toy?

Other E-textiles

Hello all! This is my first post in the community :slight_smile:

I am very new with all of this, and I am very happy that I am already playing with some sensors

I found this kind of flex sensors that work very nicely to notice when the user bends something: https://www.sparkfun.com/products/10264 BUT, I noticed they work without making any difference in the direction they are being bent.

I had a project in mind with a smart plush toy and was wondering if there is in the market some kind of bidirectional flex sensor, able to sense if the user flexed it back or forth. For instance, if there is a flex sensor that could send me a positive value when flexed in one direction and a negative value if it flexed in the other direction (back and forth).

Is there something like this? If not, what kind of sensor would you use for this kind of need? Also, homemade solutions are welcome!

Thanks a lot in advance for your help :slight_smile:

Hi there!

They are a bit expensive, but [these and [these exist.

Might be easier and a lot less expensive to use two regular flex sensors that are mounted back to back. It’s extra pins in your project but a whole lot cheaper.](https://www.sparkfun.com/products/15245)](https://www.sparkfun.com/products/15244)
