(i) Scheme illustrating the construction of enzyme/AuNCs@PAH@MnO₂ nanosheets as well as the sensing principle of nanoprobes as analytes (114). (ii) (a) Schematic images showing the wearable glucose sensor developed in a structure of kirigami-patterned mesh without strain-sensitive characteristics. (b) Metal electrodes and sensing channels based on graphene are embedded in polyimide (118). (iii) Schematic illustration showing the fabrication process of RuS₂ nanoparticles by a one-step hydrothermal method and deposition of RuS₂ NPs onto PDMS substrate applying the technique of spin coating (119). (iv) The antenna slots and the filter are inspired by the anatomy of the veins and arteries of the hand and the arm, respectively (120). (v) Top view of AgNWs on the film of LIG after stretching. The inset is the SEM image of AgNWs (121).
