1. A contact lens, comprising:
a transparent 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;
a hybrid power component that supplies two or more different types of power to the circuitry, wherein at least one of the two or more different types of power is solar power by the one or more photovoltaic cells and inductive power, wherein the one or more photovoltaic cells comprises at least one graphene photovoltaic cell,
wherein the inductive power comprises an inductive power component that receives radiofrequency energy of about 2.4 GHz in response to insufficient power from solar power and generates and provides inductive power to the hybrid power component.
