a The snowflake-shaped layout design and the photograph of the sensing circuit. b The microscopic image of the reference plate, coils, and sensing plate deployed on the sensing circuit. The photograph of (c) the folded sensing circuit and (d) the upper layer of contact lens. e Image of the integrated antenna. f (I) The flower-shaped layout design, (II) bottom surface, (III) front surface images, and (IV) microscopic image of the drug delivery circuit. g The photograph of the bottom layer lens integrated with the drug delivery circuit. Illustration of the fabrication process of (h) IOP monitoring circuit, i drug delivery circuit and the device integration. The fabrication of the sensing and delivery modulus employed a printed circuit process coupled with a cast-molding method.
