Fig. 1. ETC principle and the skin-like biosensors.

Fig. 1

(A) Schematic of the ETCs, which perform HA penetration, glucose refiltration, and glucose outward transportation. (B) Schematic of the ultrathin skin-like biosensor multilayers. (C) Thin, flexible, and biocompatible paper battery attached to the skin surface for ETC measurement. (D) Selective electrochemically deposited dual electrodes of the biosensors (left). The biosensor completely conforms to the skin surface (right).
