| description | Abstract Skin‐like bioelectronics offer a transformative technological frontier, catering to continuous and real‐time yet highly imperceptible and socially discreet digital healthcare. The key technological breakthrough enabling these innovations stems from advancements in novel material synthesis, with unparalleled possibilities such as conformability, miniature footprint, and elasticity. However, existing solutions still lack desirable properties like self‐adhesivity, breathability, biodegradability, transparency, and fail to offer a streamlined and scalable fabrication process. By addressing these challenges, inkjet‐patterned protein‐based skin‐like silk bioelectronics (Silk‐BioE) are presented, that integrate all the desirable material features that have been individually present in existing devices but never combined into a single embodiment. The all‐in‐one solution possesses excellent self‐adhesiveness (300 N m−1) without synthetic adhesives, high breathability (1263 g h−1 m−2) as well as swift biodegradability in soil within a mere 2 days. In addition, with an elastic modulus of ≈5 kPa and a stretchability surpassing 600%, the soft electronics seamlessly replicate the mechanics of epidermis and form a conformal skin/electrode interface even on hairy regions of the body under severe perspiration. Therefore, coupled with a flexible readout circuitry, Silk‐BioE can non‐invasively monitor biosignals (i.e., ECG, EEG, EOG) in real‐time for up to 12 h with benchmarking results against Ag/AgCl electrodes. |
