Title:
ELECTRICAL INTERCONNECTS IN ELECTRONIC CONTACT LENS
Document Type and Number:
Japanese Patent JP2013122591
Kind Code:
A
Abstract:
To provide a mechanically and electrically robust electronic contact lens.
Ophthalmic lenses including contact lenses may be enhanced through incorporation of both active and passive electrical components. Electrical interconnect and die attachment configurations are required to ensure electrical connectivity between the components and an optic portion of a lens as well as to provide means for mounting planar devices on spherical surfaces. Electrical interconnect and die attachment for powered ophthalmic devices including contact lenses includes realizing conductive traces on optical plastic, attaching planar dies to the spherical surfaces, and underfilling, overmolding and light blocking to complete the lens.
