(a,b) Fabrication process of the multi-walled carbon nanotube (MWCNT)-based sensors formed using flexible PDMS films having mesh-like microtrenches. (c) Scanning electron microscope (SEM) images of the developed sensors with MWCNTs embedded in the microtrenches. (d) Profiling of the microtrenches before and after the embedding process. The formed sensors were kept in (e) normal, (f) weisting positions and (g) Representation of high stretchability of the sensors. [74].
