We report the development of a micropatterned nanocomposite composed of elastomer poly(dimethylsiloxane) (PDMS) and multiwalled carbon nanotubes, and its resistive response to large mechanical deformations. Microstructures of nanocomposite were embedded into unfilled PDMS to work as a strain sensor...
