A group of interdisciplinary researchers from the Massachusetts Institute of Technology (MIT) and Northeastern University have invented a shape-shifting fiber made of LCE, or liquid crystal elastomer, coined “FibeRobo”. FibeRobo can be made directly into fabric or embedded into other preexisting materials depending on the desired effect of its application. The LCE that makes up the fiber is thermally activated, contracting up to 40%, with minimal twisting when temperature increases and reverting to its original form as the temperature decreases, all without utilizing sensory technology. This shapeshifting at a safe and comfortable temperature for individuals is made possible due to the properties of LCE; on a molecular level, LCE has liquid-like properties that, when cooled, form a periodic crystalline mass. The optimum temperature for the liquid properties of FibeRobo to be triggered can be derived from normal or slightly above body temperature.

FibeRobo also has the capability of being digitally programmed through the addition of conductive threads, allowing for its morphing to be triggered by a heated electric stimulus in comparison to exclusively body heat. Thus, when linked to an influx of data, such as information provided by sensors or a digital command placed by the wearer, FibeRobo can automatically be adjusted.

The LCE is formed into a resin-like network and squeezed by a custom fabrication machine before being cured by UV lights. The forming fiber is coated in oil before being recurred. Afterward, it is powdered to provide ease for textile manufacturers and their machinery before being spooled. The entire process takes approximately a day and creates about 3,280 feet of FibeRobo.

Furthermore, the production of FibeRobo in mass quantities would be a relatively low-cost endeavor. In testing, the production of 3.28 feet of FibeRobo cost approximately twenty cents, a remarkably low amount in comparison to the other interactive fibers currently available. as it has been determined that the fiber would be compatible with many textile manufacturing techniques, spanning from weaving looms to knitting machines. The transition of FibeRobo into mass production would be timely and relatively non-cumbersome, allowing for a near-seamless transition for designers to begin incorporating these fibers into their designs and fabrics.

FibeRobo’s variety of uses spans from medical applications to active wear. The team responsible for the fiber has already created a compression suit designed to calm dogs experiencing separation anxiety by “hugging” them…and it just so happens to be triggered by Bluetooth. They also have created a sports bra that, when detecting exercise or physical activity, is triggered to be tightened and constricted. Other potential applications of FibeRobo include adjustable outerwear insulation, self-ventilating athletic clothing, and morphable tablecloths. The researchers have expressed the desire to further adjust the chemical composition of FibeRobo to make it better for the environment or even biodegradable. They also plan on streamlining the production process so that FibeRobo can be synthesized by individuals without wet lab experience or expertise.
