Monitoring the concentration of useful biomarkers via electronic skins (e‐skins) is highly important for the development of wearable health management systems. While some biosensor e‐skins with high flexibility, sensitivity, and stability have been developed, little attention has been paid to their long‐term comfortability and optical transparency. Here, a conformable, gas permeable, and transparent skin‐like Cu 2 O@Ni micromesh structural glucose monitoring patch is reported. With its self‐supporting micromesh structure, the skin‐like glucose monitoring patch exhibits excellent shape conformability, high gas permeability, and high optical transmittance. The skin‐like glucose biosensor achieves real‐time monitoring of glucose concentrations with high sensitivity (15 420 µA cm − 2 mM − 1 ), low detection limit (50 nM), fast response time (2 s), high selectivity, and long‐term stability. These desirable performance properties arise from the synergistic effects of the self‐supporting micromesh configuration, high conductivity of the metallic Ni micromesh, and high electrocatalytic activities of the Cu 2 O toward glucose. This work presents a versatile and efficient strategy for constructing conformable, gas permeable, and transparent biosensor e‐skins with excellent practicability towards wearable electronics.
