Abstract
A substrate carries electrical components. It is bent into a non-planar shape to fit into a contact lens. For example, the substrate may be constructed from a flexible circuit board. The circuit board has certain regions for mounting electrical components. The flexible circuit board is bent into a three-dimensional shape that fits into the contact lens. The regions used to mount electrical components remain flat.

A non-planar substrate comprising a flexible circuit board bent into a three-dimensional shape that fits inside an electronic contact lens designed to be worn on a human eye, the three-dimensional shape including a three-dimensional annular band of flat facets configured to carry electrical components, wherein the flat facets meet at edge regions, with bending of the flexible circuit board at the edge regions between the flat facets.
A non-planar substrate comprising a flexible circuit board bent into a three-dimensional shape that fits inside an electronic contact lens designed to be worn on a human eye, the three-dimensional shape including a band of flat facets configured to carry electrical components, wherein the three-dimensional shape further comprises a flat extension tab that extends radially from one of the flat facets and is not coplanar with said flat facet, wherein the extension tab is configured to carry an electrical component.
A non-planar substrate comprising a flexible circuit board bent into a three-dimensional shape that fits inside an electronic contact lens designed to be worn on a human eye, the three-dimensional shape including a band of flat facets configured to carry electrical components, wherein the electrical components include semiconductor devices that are surface mounted or flip-chip mounted onto the flat facets of the circuit board and at least one of the flat facets includes a cutout to permit the semiconductor device mounted on the flat facet to protrude through the flat facet.
An electronics assembly comprising:
- a set of semiconductor devices configured for use in an electronic contact lens designed to be worn on a human eye;
- a flat flexible circuit board comprising a band of facets, wherein the semiconductor devices are mounted on the facets and conductive traces on the circuit board provide electrical connections to the semiconductor devices, and the flat flexible circuit board is bendable into a three-dimensional annular shape that fits inside an electronic contact lens, wherein the facets meet at edge regions with bending of the flexible circuit board at the edge regions between the facets;
- and
- overmolding of the facets that carry the semiconductor devices, wherein the overmolding provides additional stiffness to the flat facets, encapsulates the semiconductor devices, and isolates the semiconductor devices from a surrounding environment within the contact lens.
An electronic contact lens comprising a contact lens that contains:
- a set of semiconductor devices;
- a non-planar substrate comprising a flexible circuit board bent into a three-dimensional annular shape that fits inside an electronic contact lens, the three-dimensional annular shape including a band of flat facets meeting at edge regions, with bending of the flexible circuit board at the edge regions between the flat facets, wherein the semiconductor devices are mounted on the flat facets and conductive traces on the circuit board provide electrical connections to the semiconductor devices;
- and
- overmolding of the flat facets that carry the semiconductor devices, wherein the overmolding provides additional stiffness to the flat facets, encapsulates the semiconductor devices, and isolates the semiconductor devices from a surrounding environment within the contact lens.
A non-planar substrate that carries one or more electrical components contained in an electronic contact lens designed to be worn on a human eye, the substrate comprising a flexible circuit board bent to form a three-dimensional shape that fits inside an electronic contact lens, the three-dimensional shape comprising:
- a flat annular core portion;
- and
- one or more flat tabs that extend radially from the flat annular core portion, wherein the flat tabs are not coplanar with the flat annular core portion and the flat tabs are configured to carry electrical components.
