An example apparatus may include a display and an optical configuration configured to provide an image of the display. The optical configuration may include a lens having a lens surface that supports at least one serpentine electrode. The at least one serpentine electrode may be in electrical communication with an electrical component such as an electrooptical component (e.g., including at least one of a laser, light-emitting diode, photodiode, or image sensor) or an electroactive component that may show one or more dimensional changes under application of an electric field. An example apparatus may also include a controller in electrical communication with the electrical component through the at least one serpentine electrode. In some examples, the serpentine electrode may have an approximately sinusoidal shape. Other devices, methods, systems, and computer-readable media are also disclosed.
