Ultrastable, Omnidirectionally Stretchable, and Transparent Electrodes Based on Ag@Au Core–Sheath Nanowires with Noncoplanar Patterns for Wearable Electronics
Abstract
On-skin electrophysiological devices require stretchable transparent electrodes offering omnidirectional compliance, stable conductivity, environmental resilience, and high transparency. Herein, we present hierarchical, environmentally robust omnidirectionally stretchable transparent electrodes (OSTEs) using Ag@Au core–sheath nanowires (Ag@Au NWs). Fabrication employs reusable hydrophobic masks to pattern 2D geometries on prestrained substrates; strain release self-assembles 3D wrinkled architectures. Combined with salt-assisted NW cold-welding, this enables exceptional multidirectional stretchability and strain-tolerant conductivity. The optimized OSTE achieves 9.24 Ω/sq at 75.0% transmittance, withstands >10,000 cycles of 30% uniaxial strain (resistance increase
