A product that can diminish to fit around internal organs without squashing them might be utilized to keep an eye on electrical activity in the body. It contracts to less than half of its preliminary length when damp, and can adhere around the organs’ irregular shapes.
Junqi Yi at Nanyang Technological University in Singapore and her associates made this product, called WRAP, from a petroleum-derived polymer comparable to plastic. They tuned its molecular structure to imitate that of spider silk, which reduces when damp. The shrinking occurs in both these products since water interrupts bonds in between chains of extended particles that then recoil.
Throughout a number of experiments, when the scientists included water to WRAP, it end up being softer and stretchier, contracting as much as 65 percent in length. A dry loop of the product with a size of 17 centimetres diminished to 8 millimetres in size.
