Adaptive Phase‐Locked E‐Skin for Sports Physiology and Medicine

Abstract The pursuit of creating materials that replicate the flexibility, stability, and advanced perceptual capabilities of human skin, attributes honed through natural evolution, represents a long‐term objective in pioneering fields such as electronic skin (e‐skin) research. However, conventional e‐skin often struggles with stability and functionality in harsh sports environments, resulting in the degradation of the intimate interface over time. Inspired by the innate biphasic structure of human subcutaneous tissue, an adaptive phase‐locked e‐skin (APLE) is presented, designed to seamlessly conform to dynamic sports environments, offering robust applications in sports physiology and medical contexts without malfunctioning. The APLE allows one to laminate onto the skin with consistent homeostasis, providing a foundation for advancing data‐driven sports physiology and creating personalized sports plans. Additionally, APLE offers immediate on‐site medical treatment for common sports injuries, including hemostasis and sutureless wound closure. Ultimately, the reported multifunctional e‐skin can provide significant value in managing sport‐related burdens through digital and people‐centered physiology monitoring, along with real‐time sport healthcare.
