Liquid Metals: Stretchable, High‐<i>k</i> Dielectric Elastomers through Liquid‐Metal Inclusions (Adv. Mater. 19/2016)

Abstract

An all-soft-matter composite consisting of liquid metal microdroplets embedded in a soft elastomer matrix is presented by C. Majidi and co-workers on page 3726. This composite exhibits a high dielectric constant while maintaining exceptional elasticity and compliance. The image shows the composite's microstructure captured by 3D X-ray imaging using a nano-computed tomographic scanner.
