The testing has shown the composite can be extended as much as 400 % during which the electrical resistance increases more than 270 times. The high strain sensing can be attributed to the network cracking upon extension. To understand the cracking mechanism and explain the resistance change, the structural changes of networks made of pristine as well as functionalized multiwalled carbon nanotubes were examined. The microscopic observation of crack formation and resistance change of the networks correlates well with the number of cracks.
