High‐Conductivity Elastomeric Electronics

Abstract

Stretchable electronic circuits have been microfabricated using tortuous gold wires embedded in silicone elastomer. With appropriate geometric parameters, the wires could elongate by more than 50 % while maintaining stable conductivity (see Figure). This technology represents a key development towards conductive fabrics, flexible displays, and other applications that require electronics to withstand unprecedented degrees of stress and vibration.
