Abstract
A body-mountable retinal sensing device includes an electrochemical sensor embedded in a polymeric material configured for mounting to a body surface, such as a cornea. The electrochemical sensor includes a working electrode, a reference electrode, and a reagent localized near the working electrode that selectively reacts with retinal. Application of a voltage between the working electrode and the reference electrode causes a current related to a concentration of retinal in a fluid to which the electrochemical sensor is exposed. The current is measured by the body-mountable device and wirelessly communicated.
