Innovations in spider silk‐inspired artificial gel fibers: Methods, properties, strengthening, functionality, and challenges

“…368 Stretchable fiber-or yarnshaped piezo-resistive sensors with a coaxial structure are typically made by wet spinning, soakage, coating, spraying, polymerizing, or applying other mixed nanostructures to the surface of stretchable fibers, like PU, Ecoflex, and polydimethylsiloxane, to produce nanoscale roughness that allows for high sensitivity and quick response times in the sensors. [369][370][371][372][373] The majority of these sensing devices and materials need expensive, multi-step engineering methods, despite their excellent performance and practicality. 374 Additionally, most materials that conduct electricity are coated on the surface of the fiber with lower interfacial adhesion.…”
