    Abstract: A device includes a contact lens, a corneal sensor that includes a circular trace of conduction paths located at or near an outer peripheral edge of the contact lens that surrounds an unobstructed area at a center region of the contact lens, and a connection wire coupled to the corneal sensor and configured to electrically couple to an external data acquisition system. Methods of fabricating the device may include providing a thin device that includes a sensor and a connection wire coupled to the sensor, transferring the sensor to a curvilinear inner surface of a contact lens, 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 sensor to anchor the sensor to the inner surface of the contact lens.

    Abstract: An ink and method of conducting an examination suitable for reducing the likelihood that the students' answers on paper-based examinations may be changed at a later time prior to being graded. The ink includes a solution of marking particles, a suspension material, and a preserving material. A mark made with the ink is initially erasable for a predetermined period of time after the mark is formed and after the expiration of the predetermined period of time the mark is not erasable. The method of conducting an examination includes providing an ink to an individual, and then providing questions to an individual wherein the individual indicates answers to the questions by producing marks with the ink.
