by Researchers at MIT and Northeastern University have developed a groundbreaking low-cost, shape-shifting fiber that can contract and resume its original shape when subjected to heat. Unlike previous shape-changing fibers that required additional hardware or sensors, this new fiber, called FibeRobo, is compatible with existing textile manufacturing machinery, making it practical for real-world applications.
The development of shape-changing fibers has been a major focus for researchers, as they have the potential to revolutionize various industries, from fashion to aerospace. The ability to incorporate these fibers into textiles could create new possibilities for adaptive and responsive materials. However, the use of additional hardware has hindered the practicality of these fibers outside of the laboratory setting.
To address this challenge, the researchers turned to liquid crystal elastomer (LCE) to create FibeRobo. Liquid crystals are molecules that can flow like liquid but can also stack into a crystal arrangement when allowed to settle. By incorporating these crystal structures into a stretchy elastomer network, the researchers were able to create a fiber that contracts when exposed to heat and reverts to its original shape when the heat is removed.
The manufacturing process involves squeezing heated LCE resin through a nozzle and curing it with UV light to create the fiber. The fiber is then coated in oil and cured again with strong UV light to ensure its strength and smoothness. It can be easily incorporated into textile manufacturing machines without any modifications. The entire process, from chemical synthesis to finished spool, takes approximately a day and produces about a kilometer of ready-to-use fiber.
One of the key advantages of FibeRobo is its low cost. It can be produced for as little as 20 cents per meter, which is about 60 times cheaper than commercially available shape-changing fibers. Furthermore, it can contract up to 40% without bending, making it ideal for various applications.
The researchers have already demonstrated the capabilities of FibeRobo by creating a compression jacket for a dog that can hug the pet using a Bluetooth signal from a smartphone. They also developed an embroidered adaptive sports bra that tightens when the user begins exercising. These examples showcase the potential for FibeRobo in creating innovative and functional products.
The team has plans to make FibeRobo’s chemical components recyclable or biodegradable and simplify the polymer synthesis process so that users without extensive lab expertise can produce it. The ultimate goal is to make FibeRobo widely available for consumers, allowing them to purchase it from craft stores and create their own products with shape-shifting capabilities.
In conclusion, the development of the shape-shifting fiber FibeRobo has the potential to revolutionize the textile industry. Its compatibility with existing manufacturing machinery, low cost, and versatile applications make it an exciting advancement in adaptive and responsive materials. As further research and development are conducted, FibeRobo could become a game-changer in the world of textiles.
