Compression‐Durable Soft Electronic Circuits Enabled by Embedding Self‐Healing Biphasic Liquid‐Solid Metal Into Microstructured Elastomeric Channels

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

Abstract Compression strongly degrades the electrical conductivity of liquid‐metal‐based circuits because liquid state is prone to be squashed. Here, a new compressible and stretchable biphasic liquid‐solid self‐healing circuit proposed by filling GalnSn‐BilnSn metal into micropillar‐embedded channels. The underlying BilnSn solid alloy layer serves as compression resistance layer, while upper GalnSn enables real‐time cracks in under large deformations, resulting autonomous maintenance both stretching compression. embedded micropillars further improved durability providing additional mechanical support. synergistic effect between materials micropillar designed conductor show stable performance (R/R 0 <10) pressure 38.2 MPa (≈389.5 Kgf cm −2 ) cyclic 15.8 over 7000 cycles <0.48%) without compromising stretchability, whereas metal‐based can only endure up 2.5 (25.49 ). antenna hybrid fabricated using showed enhanced durability. structure‐confined strategy enabled high‐resolution scalable manufacturing. Overall, robust stability significantly expands range possible applications conductors soft electronics.

Abstract The thermoelectric (TE) effect, capable of directly converting heat into electrical energy, has catalyzed the development numerous next‐generation functional devices. However, traditional TE generators (TEGs), predominantly composed rigid materials, are unable to maintain synchronous deformation under bending, twisting, or stretching, thereby limiting their application potential. Liquid metal (LM), with its exceptional conductivity, flexibility, thermal self‐healing properties, and unique effects, presents a compelling alternative as conductive heat‐transfer material.
