Abstract
One aspect of the present disclosure relates to a remotely controllable lens device. The lens device can include a lens material and a circuit physically coupled to the lens material. The circuit can be configured to be powered based on an energy signal from a power source to perform a function (e.g., release of drug, generation of electromagnetic radiation, detection of electromagnetic radiation, and/or control of an optical refractive property). For example, the power source can be an external power source and/or an auto-powered source. The external power source can be, for example, a power source that utilizes synchronized magnetic flux phase coupling (e.g., WiTricity). The auto-powered source can be provided on-site (e.g., on-chip) using a harvesting system (e.g., solar-cell, photo-cell, piezoelectric, etc.)
