News from Optical Materials Express: Stretchable waveguides maintain stable transmission even when bent or twisted. A new design helically winds deformable metallic wires onto thermoplastic polyurethane to create flexible waveguides, improving mechanical stability and achieving both elastic recovery and excellent compatibility with fabric and skin. The approach could enable adaptive wireless communication, body-compatible sensors and conformal devices that seamlessly interface with biological tissues or dynamic surfaces.
