We currently use an MSI laminated piezo film strip sandwiched between a cover plate and the vehicle to detect contact between a given surface of the vehicle and anything else in its surroundings (MSI P/N 1-1002405-0). We have a new project that requires a smaller sensor. Basically, the intended sensing area is .42" x .5", but the .42" is the limiting dim'n, it represents the spacing between two fasteners, which cannot be changed for the purpose of this test. We would like to stick with something very similar to what we have, does anyone know where I can look... I have not had any luck in the MSI catalog and with Google?

One more question on piezo strips:

What happens if you overload it?
