Next generation textile-based stretchable electronic devices

Tinuku - Inspired by spider silk, the researchres propose to develop a simple spinning method hydrogel fibers with ordered and reversible chain alignment from aqueous solution of polyelectrolytes at ambient conditions.

Reported on Penelitian, Mingming Ma of the University of Science and Technology of China in Anhui and colleagues show a simple spinning method to prepare conductive hydrogel fibers with ordered polymer chain alignment that mimics the hierarchically organized structure of spider silk.

The as-prepared sodium polyacrylate hydrogel fiber is further coated with a thin layer of polymethyl acrylate to form a core–shell water-resistant MAPAH fiber. Owing to the coexistence and reversible transformation of crystalline and amorphous domains in the fibers, MAPAH fibers exhibit high tensile strength, large stretchability and fast resilience from large strain.

MAPAH fiber serve as a highly stretchable wire with a conductive hydrogel core and an insulating cover. The stretchability and conductivity of the fiber are retained at -35C. As a prime example of stretchable conductive fibers, MAPAH fibers will shed light on the design of next generation textile-based stretchable electronic devices.
