Contact lens having sensors and methods for producing the same

A method comprising:

• providing a glass substrate coated with a water-soluble layer;
• depositing elastomeric materials on the water-soluble layer of the glass substrate to simultaneously form a circular trace and a connection wire coupled to the circular trace, wherein the elastomeric materials includes silver flake-filled polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene (AgSEBS) and at least one layer of the circular trace and at least one layer of the connection wire define an integral conduction path;
• removing the water-soluble layer with deionized water to separate the circular trace and the connection wire from the glass substrate;
• electroplating the circular trace with gold or an alloy thereof;
• transferring the circular trace to a curvilinear inner surface of a contact lens configured to face a user's eye when worn;
• feeding the connection wire through the inner surface of the contact lens and out of an outer surface of the contact lens;
• and
• performing electrochemical polymerization of a conducting polymer material over the circular trace to anchor the circular trace to the inner surface of the contact lens, the conducting polymer material being doped poly(3,4-ethylenedioxythiophene) (PEDOT) and the conducting polymer forming a conduction encapsulation layer around the entire surface of the circular trace;
• wherein the circular trace is configured to function as a corneal sensor and the connection wire is configured to couple the corneal sensor to an external data acquisition system.
