Researchers from MIT have developed a programmable fiber called Fiberobo that has the ability to change its shape based on temperature fluctuations. This innovative fiber can become more isolating when the temperature drops, helping to maintain heat. Fiberobo is designed to be compatible with textile production techniques and can be continuously produced in long lengths. This opens up possibilities for incorporating sensors and other relevant technologies into a wide range of fabrics.
In addition to shape-shifting, Fiberobo can also be combined with a conductive thread, which allows it to function as a heating element when electricity passes through it. This means that textiles made with Fiberobo can be digitally controlled to provide additional user comfort and versatility.
Jack Forman, a graduate student from MIT Media Lab’s Tangible Media Group, highlights the inert nature of textiles and the potential for them to be adaptive and responsive. The researchers will be presenting their study at the ACM Symposium on User Interface Software and Technology.
One of the key advantages of Fiberobo over other similar fibers is its compatibility with conventional textile production procedures. Many shape-changing fibers struggle to integrate into textiles outside of laboratory conditions. However, the MIT researchers were able to create Fiberobo using liquid crystal elastomer (LCE), a material that allows for silent activation and shape-changing ability. This fiber can be reduced by 40% without bending, activated at safe temperatures for the skin, and costs only 20 cents per meter.
To demonstrate the potential applications of Fiberobo, the MIT researchers showcased an adaptive sports bodice that adjusts its shape when the user engages in physical activity. In the future, the team aims to further develop the fiber’s chemical components to allow for biodegradability and easier processing.
