Highly stretchable conductive polypyrrole film on a three dimensional porous polydimethylsiloxane surface fabricated by a simple soft lithography process

We create an elastic porous polydimethylsiloxane highly stretchable conductive substrate. The surface is fabricated by a simple soft lithography process that replicates the 3D corrugated porous microstructures from a low-cost commercially available abrasive paper.
