Abstract:
1. A sensor system for determining control signals of a ciliary muscle of an eye having a cornea, a lens a pupil, an iris, ciliary muscles, comprising Müller muscles, and Brück muscles and zenular fibers, the sensor system comprising: a) a contact element consisting of an electrically non-conductive material for disposition on the cornea in contact with the area of the eye around the iris thereof, b) a sensor system with at least one sensor applied to the contact element in an annular array around the iris, and c) a signal processing arrangement disposed on, or in, the contact element, d) each sensor comprising at least three electrodes oriented in the same direction and arranged in a row, e) the orientations comprising at least one orientation extending in a radial direction with respect to the iris and f) each sensor having an intermediate electrode which forms a reference potential and two electrodes which are disposed in the orientation direction directly adjacent to, and at opposite sides of, the intermediate electrode and which determines an eye body potential with respect to the reference potential.
