Abstract
Systems and methods are described that relate to a device, such as an eye-mountable device. The eye-mountable device may include a capacitance sensor and associated circuitry configured to measure a capacitance and/or a change in capacitance based on a material being in proximity with the capacitance sensor. For example, the capacitance sensor and associated circuitry may be operable to detect an eye-related movement of a wearer of the eye-mountable device. The eye-related movement may be a blink, a wink, an eye moving with respect to an eyelid, an eyelid moving with respect to the capacitance sensor, or an eyelid closing. At least one sensor electrode of the capacitance sensor may operable to carry out an additional function, e.g. to measure a level of glucose in tear-fluid or to provide wireless communication.
