The development of stretchable electronics is essential for advancing wearable healthcare and biomedical devices . While significant progress has been made in materials and designs for stretchable conductors, scalable and versatile fabrication routes remain a key challenge for widespread adoption . Current approaches often require complex processing steps and specialized equipment , or face fundamental limitations in scalability and manufacturability . Several distinct strategies can be used to create stretchable conductors, which can usually be classified into five distinct categories: microcracked films , patterned interconnects , intrinsically conductive polymers , liquid metals , and stretchable composites . Microcracked metal films make use of controlled crack formation in thin metal films Laboratory of Biosensors and Bioelectronics, ETH Zürich, Gloriastrasse 37/39, Zürich, Switzerland † Supplementary Information available: [details of any supplementary information available should be included here].

However, achieving reliable and reproducible crack patterns remains challenging , rendering their stretchability limited. Geometrically designed structures, such as serpentine, fractal or kirigami patterns effectively redistribute strain through out-of-plane deformation, enabling high stretchability . While powerful, this approach faces fundamental limitations in miniaturization, as the mechanical advantages diminish at smaller scales . Additionally, achieving high-density features while maintaining stretchability presents significant design and fabrication challenges . Liquid metals, primarily based on gallium alloys, offer intrinsic deformability while maintaining metallic conductivity . Recent developments have improved patterning capabilities and enabled higher resolution features . Nevertheless, these materials face ongoing challenges in biocompatibility and long-term stability , particularly for biomedical applications . Organic conductors, such as PEDOT:PSS and its derivatives, provide another materials-based solution . While offering intrinsic deformability and compatibility with solution processing , these materials typically exhibit lower conductivity compared to metallic conductors , and often face stability issues in ambient conditions for biomedical applications . Stretchable composites use nanomaterials such as nanowires , or nanoparticles as filler in a stretchable matrix, and have demonstrated impressive combinations of electrical and mechanical properties . However, the fabrication process often involves complex synthesis protocols and challenges in achieving uniform assembly over large areas , limiting scalability.
