Integrated bioelectronics with conformal adhesion interfaces on dry/wet biosurfaces and water-repellent stretchable electric elements are in high demand for reliable real-time diagnostics of the dynamic human body. Here, the authors present a diving beetle-inspired electro-adhesive patch with mechanically robust nanowire-implanted conductive multiscale architectures that provides a skin-adaptable, isotropically stretchable interface for a multiple-biosignal monitoring device. Using a facile all-solution-based process, a hydrophobic, stretchable carbon-nanotube-implanted conductive composite electrode on insect-like adhesive architectures is fabricated. The conductive adhesive patch with bioinspired wrinkled microsuction cups exhibits remarkable enhanced wet adhesion with sweat-drainability, as well as high stretchable electrical performance under tensile strain in dry and wet conditions. Owing to the high durability and softness of the bioinspired electric adhesive patch, its performance is successfully maintained even with repeated attachment (<1000 cycles) and mechanical stretching. To demonstrate a multiplexed wearable device, a temperature-sensitive conductive material is coated onto the isotropically strain-insensitive stretchable electrode to allow simultaneous electrocardiogram and temperature measurements on soft skin in dry and wet environments.
