Ophthalmic lens assembly having an integrated antenna structure
Antennas and antenna systems may be designed and configured for incorporation into mechanical devices, including medical devices, such as ophthalmic devices, including contact lenses. These antennas and antenna systems may be utilized to transmit data from the mechanical device to a receiver, to receive data from a transmitter, and/or to inductively charge an electromechanical cell or the like incorporated into the mechanical device.
1. An ophthalmic lens assembly comprising:
a lens configured for placement in at least one of the inside of an eye or on the surface of an eye, the lens including an optic zone configurable for at least one of vision correction and vision enhancement and a peripheral zone;
a stacked die structure comprising one or more substrate layers each having an upper and lower surface, the one or more substrate layers having an annular configuration;
one or more mounting structures attached to at least one of the upper and lower surfaces of the one or more substrate layers;
one or more electronic components attached to the one or more mounting structures, the electronic components configured to control the functionality of the lens; and
at least one antenna arrangement operatively associated with the one or more electronic components and configured for at least one of the transmission of signals between the one or more electronic components and an external device, the reception of signals between the one or more electronic components on an external device, and inductive coupling, the at least one antenna arrangement being affixed to at least one of the upper and lower surfaces of the one or more substrate layers and isolated to reduce parasitic capacitance, wherein the stacked die structure, the one or more mounting structures, the one or more electronic components and the at least one antenna are encapsulated in the peripheral zone of the lens, the stacked die structure being configured to arrange the one or more substrate layers such that all components fit within the peripheral zone.
2. The ophthalmic lens assembly according to claim 1 , wherein the lens comprises a contact lens.
3. The ophthalmic lens assembly according to claim 1 , wherein the lens comprises an intraocular lens.
4. The ophthalmic lens assembly according to claim 1 , wherein the lens comprises a spectacle lens.
5. The ophthalmic lens assembly according to claim 1 , wherein the at least one antenna arrangement comprises one or more single-turn loop antennas.
