Abstract

Disclosed herein is a composite comprising an elastomer with an embedded network of liquid metal inclusions. The composite retains similar flexibility to that of an elastomer but exhibits electrical and thermal properties that differ from the properties of a homogeneous elastomer. The composite has applications for wearable devices and other soft matter electronics, among others.
