The research is published in the journal Polymer. Biocompatible and tailor-made A decisive factor that turns a conventional textile fiber into a medical product is the material of the fiber sheath ...

the new fiber has a gallium metal core – a wire, in other words – which is surrounded by a SEBS (styrene-ethylene-butylene-styrene) elastic polymer sheath. When subjected to mechanical stress ...

"This novel combination of buckling in two dimensions avoids misalignment of nanotube and rubber core directions, enabling the electrical resistance of the sheath-core fiber to be insensitive to ...

A decisive factor that turns a conventional textile fiber into a medical product is the material of the fiber sheath. The team chose polycaprolactone (PCL), a biocompatible and biodegradable polymer ...

Like polar bear hair, the fiber’s core is filled with thousands of pores — tiny pockets of air that help prevent heat loss — and surrounded by a flexible, waterproof sheath. But unlike hair ...

The final step of production involves applying a black sheath made of durable polyethylene. A finished fiber-optic cable can be up to 30,000 feet long, or more than 5 miles. Out in the world ...
