These are self-healing stretchable wires formed by embedding liquid metal alloy in microchannels composed of self-healing polymer. These stretchable wires can be completely severed with scissors and rapidly self-heal both mechanically and electrically at ambient conditions. By cutting the channels strategically, the pieces can be re-assembled in a different order to form complex microfluidic networks in 2D or 3D space. This work was done in the Chemical and Biomolecular Engineering Department at NC State University and appears in the journal Advanced Materials.
