Step 8What you can do with a knit stretch sensor?
You can use it as in inflation sensor. Inflate a regular party balloon inside the knit tube and use and LED to visualize the change in resistance. See video and pictures for reference.

nice instructable.
Let me share my ideas for this sensor.
In principle it's a way sensor, which gives you a value for the stretching from start to finish, right?
I would suggest to pull the "sleeve" over a plastic tube, add a tension spring in the center of the tube, and that way you have a defined force-resistance-relationship for a force sensor, or a scale.
Another nice application could be two balloons in a "hour glass like" construction. Each balloon is cover with a sensor-sleeve and one is filled with time-sand (be careful to order original, calibrated time sand).
as soon as the lower one has expanded enough, the hour glass turns around, and fills up the lower balloon.
This can be used as hour glass, or as kind of new lava lamp.
so far
