Abstract

Stretchable electronic devices have attracted considerable attention as enabling technologies for wearable healthcare, soft robotics, and human–machine interfaces. However, conventional fabrication of multilayer soft electronics relies on repetitive printing, stacking, and sealing processes, resulting in complex manufacturing procedures and reduced mechanical reliability due to interfacial delamination under repeated deformation. Here, we present a programmable self-embedded multilayer liquid metal printing strategy that enables the direct fabrication of monolithic three-dimensional electronic architectures within a single elastomer matrix. By exploiting the mechanical competition between the gravitational force of the printed liquid metal and the yield stress of the uncured polymer, the embedding depth of the liquid metal was precisely controlled, thereby establishing a fundamental mechanism for forming programmable multilayer circuits without additional transfer or stacking processes. In addition, vertically interconnected multilayer circuits were realized without any post-sintering process while preserving the intrinsically high electrical conductivity of liquid metal. To demonstrate the versatility of the proposed platform, vertical interconnect structures, multilayer capacitive pressure sensors, and three-dimensional inductive coils were fabricated within a monolithic elastomer. The resulting multilayer and three-dimensional architectures effectively enhanced device performance. This work establishes a scalable manufacturing strategy for monolithic soft electronic systems by significantly simplifying the fabrication process, enabling diverse applications in next-generation stretchable electronics, soft robotics, and human–machine interfaces.
