(i) Physical image of an artificial human hand with In₂O₃ FET foil amounted on it (105). (ii) Schematic illustration showing integrated contact lens attached to an artificial eye to detect glucose concentration in tears. Wearable glucose sensing patch remained in contact with the skin under relaxation and tension (106). (iii) Conceptual image showing the application of self-powered wearable non-invasive glucose sensing system (107). (iv) Schematic diagram showing the wearable glucose sensor based on Cu₂O@Ni micromesh film is attached to the skin for glucose detection in real-time (108).
