Skin-integrated electronics are a novel type of wearable devices that are mounted on the skin for physiological signal sensing and healthcare monitoring. Their thin, soft, and excellent mechanical properties (stretching, bending, and twisting) allow non-irritating and conformal lamination on the human skin for multifunctional intelligent sensing in real time. In this review, we summarise the recent progress in the intelligent functions of skin-integrated electronics, including physiological sensing, sensory perception, as well as virtual and augmented reality (VR/AR). The detailed applications of these electronics include monitoring physical- and chemical-related health signals, detecting body motions, and serving as the artificial sensory components for visual-, auditory-, and tactile-based sensations. These skin-integrated systems contribute to the development of next-generation e-eyes, e-ears, and e-skin, with a particular focus on materials and structural designs. Research in multidisciplinary materials science, electrical engineering, mechanics, and biomedical engineering will lay a foundation for future improvement in this field of study.
