Mechanically Reprogrammed Coaxial Fibers for Multiphysics Transduction and Human-Machine Interfaces. [PDF]
Adv Sci (Weinh)A continuously wet‐spun coaxial fiber is developed to combine stretchable conductivity, resistive sensing, and self‐powered triboelectric sensing in a single architecture. A mechanically reprogrammed dual‐network sheath stabilizes large deformation and improves signal reliability. These fibers can be woven into textile interfaces for multichannel touch
