Advances in stretchable electronics offer the possibility of developing skin-like motion
sensors. Carbon nanotubes (CNTs), owing to their superior electrical properties, have great
potential for applications in such sensors. In this paper, we report a method for deposition
and patterning of CNTs on soft, elastic polydimethylsiloxane (PDMS) substrates using
capillary action. Micropillar arrays were generated on PDMS surfaces before treatment with
plasma to render them hydrophilic. Capillary force enabled by the micropillar array spreads …
