Abstract
Apparatus, systems and methods of contact lenses with power sources are provided. In some aspects, a contact lens can include a substrate; and a circuit. The circuit can include: one or more sensors disposed on or within the substrate; circuitry disposed on at least a portion of the substrate; one or more photovoltaic cells disposed on at least a portion of the substrate; and a hybrid power component that supplies at least one of two or more different types of power to the circuitry, wherein at least one of the two or more different types of power is radio frequency/inductive power. In various aspects, other types of power can be solar and/or microelectromechanical system power. Additionally, in various aspects, photovoltaic cells can be arrayed in different configurations and/or over a significant portion of a viewing surface of the contact lens. In some aspects, the photovoltaic cells can be transparent.
