Yale University’s research team has developed a new type of “robot fabric” that can change its shape and hardness according to demand or by sensing the environment. In the future, the material can be used in high-tech clothing, self-made tents or robot parachutes. In order to make the fabric have different functions, they have different functions. The first fiber is an epoxy resin filled with alloy particles called field’s metal, which has a relatively low melting temperature of 62 ℃ (144 ° f). This means that it can be gently heated to make the fabric soft and malleable, and then cooled to room temperature to lock it into a specific shape. < / P > < p > Trevor Buckner, lead author of the study, said: “epoxy composites made of field metal can be as soft as latex rubber or as hard as hard acrylic acid, and the long fibers of this material can be sewn onto the fabric to give it a supporting framework, and we can open and close it.”. < / P > < p > with this technology, the team was able to make their smart materials load-bearing, able to withstand a weight of 50 grams (1.8 ounces), which normally flattens the fabric directly. The team also applied a conductive ink that could be applied to fabrics, created sensors that could detect environmental changes and allow materials to react accordingly. Rebecca Kramer bottiglio, co-author of the study, said: “conductive composites self coagulate around individual fibers and do not significantly change the porosity of the fabric. The sensor is visible, but does not change the texture or permeability of the fabric, which is important for the comfort of wearable applications. “. < / P > < p > finally, the team added a shape memory alloy (SMA) to allow the material to change shape and move. This kind of thing can be programmed to remember a specific shape, so that after it is deformed, it can be triggered to jump back to its original shape. In this case, the researchers flattened the SMA wires into ribbons, so they could restore the fabric to a flat shape as needed.
