▎ 摘  要

NOVELTY - A deformable circuit component comprises an electrical element containing microcapsules having electrical properties. The microcapsules comprise a gallium liquid metal alloy core containing 60-85 wt.% gallium alloying metal(s) and a polymeric shell encapsulating the liquid core. The polymeric shell having conductive properties, comprises a coating of an electrically conductive material and/or incorporates an electrically conductive material selected from silver particles, gold particles, copper particles, gallium particles, indium particles, gallium/indium alloy particles, mercury particles, aluminum particles, polythiophene, poly(ethylenedioxythiophene), polyaniline, graphene, carbon nanotubes and/or fullerenes. USE - Deformable circuit component is used in electrical applications. ADVANTAGE - The polymeric shell present in the liquid metal of the flexible circuit materials, has elasticity to provide mechanical resiliency, while providing a protective layer against conducive fluid coalescence. For applications requiring electrically intimate contact, the polymeric shell is electrically conductive, and for applications where the contact is required to be ionically conductive, the elastomer of the polymeric shell is chosen to be ionically conductive. The encapsulation of liquid conductor within thin conductive polymeric shell, provides a superior material solution to applications that require a mechanical resiliency and conductivity, than a conductive elastomeric polymer devoid of a liquid metal core.
