FibeRobo is a novel body-temperature shape-changing fiber based on liquid crystal elastomers. The development of a new fabrication technique and chemical composition of the fiber enables self-reversing morphing at, or optionally slightly above, body temperature. These fibers, once formed into the larger textile structure through knitting, weaving, and sewing techniques, enables a myriad of applications from medical devices (compressions shirts), athletic wear (self-ventilating clothing), to interactive eating experiences (morphing table cloths), and transforming fashion pieces.
