Abstract
An active contact lens system (100) and method for fabricating an active contact lens (200) are disclosed. The system comprises an active contact lens (110) worn like a conventional contact lens, and comprising a transparent substrate (112) having a circuit formed of one or more of a semi-transparent display (114), a display drive circuit (116), a data communications circuit (118), one or more biosensors (122), an energy transfer antenna (120) and an interconnect network (124). The substrate may be a conventional contact lens material, such as PMMA or RGP, and the display may be formed from a plurality LEDs. A method for fabricating the active contact lens includes fabricating the template (202), forming solder compatible pads (204), assembling the circuit elements (206) and micro-molding the lens (208). The template is fabricated with an interconnect network and shape-specific recesses for receiving the circuit elements. Preferably, the assembly is done using fluidic self-assembly.
