It's was something of a cumbersome project though, needing a 3D printer and special heat-resistant plastic giving of carcinogenic fumes during printing. To be blunt it was also not very mobile and interpreting the results was further cumbersome Recently though, I've been told that Arduino, and it's various sensor packages, has matured to the point where it's a usable alternative.

I am looking for something that will last at least 100 stretch cycles and is not messy, so for example liquid based colloidal stuff won't be suitable.
