Highly Stretchable and Strain‐Insensitive Liquid Metal based Elastic Kirigami Electrodes (LM‐eKE) (Adv. Funct. Mater. 30/2023)

Abstract

Elastic Kirigami In article number 2301388, a liquid metal (LM) based elastic Kirigami Electrode (LM-eKE) architecture is demonstrated by Carmel Majidi, Tae-il Kim, and co-workers that is electrically conductive and can be stretched beyond the limits of traditional kirigami designs. The electrodes are composed of a biphasic film of gold and gallium-indium LM alloy on a kirigami patterned silicone substrate. The coupling between geometric and elastic deformation allows the LM-eKE to maintain highly stable electrically conductive pathways that reduces motion artifacts when collecting physiological data.
