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. ## Claims ### Claim 1 A contact lens, comprising: a substrate; and a circuit comprising: one or more sensors disposed on or within the substrate; circuitry disposed on or within at least a portion of the substrate; one or more photovoltaic cells disposed on or within at least a portion of the substrate; and a hybrid power component disposed on or within the substrate, wherein the hybrid power component selects at least one of two or more different types of power based on at least an operation of the circuitry or an environment of the contact lens and supplies the selected at least one of two or more different types of power to the circuitry, wherein one of the two or more different types of power is photovoltaic power provided by the one or more photovoltaic cells. ### Claim 2 (depends on 1) The contact lens of claim 1, wherein the one or more sensors sense at least one of pressure, light, acceleration, temperature or strain. ### Claim 3 (depends on 1) The contact lens of claim 1, wherein another one of the two or more different types of power is radio frequency/inductive power. ### Claim 4 (depends on 3) The contact lens of claim 3, wherein the hybrid power component supplies the radio frequency/inductive power and the photovoltaic power intermittently. ### Claim 5 (depends on 1) The contact lens of claim 1, further comprising one or more microelectromechanical systems and wherein another one of the two or more different types of power is electric power provided by the one or more microelectromechanical systems. ### Claim 6 (depends on 5) The contact lens of claim 5, wherein the hybrid power component supplies the photovoltaic power and the electric power from the one or more microelectromechanical systems intermittently. ### Claim 7 (depends on 1) The contact lens of claim 1, further comprising a power storage component that stores power from the one or more photovoltaic cells. ### Claim 8 (depends on 7) The contact lens of claim 7, wherein the power storage component comprises a storage capacitor. ### Claim 9 (depends on 7) The contact lens of claim 7, wherein the power storage component comprises a thin film battery. ### Claim 10 (depends on 1) The contact lens of claim 1, wherein the one or more photovoltaic cells are translucent or transparent. ### Claim 11 (depends on 10) The contact lens of claim 10, wherein the one or more photovoltaic cells are disposed over at least half of a surface of the substrate. ### Claim 12 (depends on 1) The contact lens of claim 1, wherein at least one of the one or more photovoltaic cells or the circuitry is disposed along a perimeter of the substrate. ### Claim 13 (depends on 1) The contact lens of claim 1, wherein the one or more photovoltaic cells comprise a circular array of two or more photovoltaic cells. ### Claim 14 (depends on 1) The contact lens of claim 1, wherein the hybrid power component supplies at least two of the two or more different types of power to the circuitry and alternates between supplying a first one of the at least two of the two or more different types of power and supplying a second one of the at least two of the two or more different types of power.
