A Programmable Island‐Bridge Configuration for Constructing Ultra‐Stretchable Conductors

Abstract The rapid advancement in stretchable electronics necessitates stable and highly stretchable conductors. In this work, a novel approach using the Programmable Island‐Bridge Configuration (PIBC) is introduced to develop ultra‐stretchable conductors that feature tunable stretchability and conductivity. The PIBC utilizes liquid metal, known for its excellent conductivity and shape adaptability, as the island component, and 1D nanoconductors as the bridges. This combination constructs highly robust, ultra‐stretchable conductors through dynamic self‐assembly. Capable of accommodating various strain levels, these conductors maintain an ultrahigh conductivity of 1.15 × 10 6 S m −1 at a strain of over 2,200%. This achievement marks a significant milestone in the field of stretchable electronics, offering substantial contributions to the community.
