THIN AND FLEXIBLE SEMICONDUCTOR ELEMENTS ON THREE-DIMENSIONAL SURFACES Russian patent published in 2018 - IPC A61F9/00 

FIELD: medicine.

SUBSTANCE: ophthalmic electronic device comprises: a rigid three-dimensional substrate of a circular shape that is configured and sized to be positioned in a contact lens arranged to be positioned on the eye; electrical contacts made on the surface area of the rigid three-dimensional substrate; and at least one electronic element comprising a thin flexible semiconductor attached and fixed to the electrical contacts. The rigid three-dimensional substrate contains a surface region that is non-planar at the macroscopic level along its length and contains a plurality of valves with a space between adjacent valves that provides their flexibility. At that, the rigid three-dimensional substrate comprises a central portion for the electroactive optical portion. A thin flexible semiconductor is matched to a macroscopically nonplanar surface of the rigid three-dimensional substrate. Method for obtaining of an ophthalmic electronic device includes the steps of: formation of a rigid three-dimensional substrate, attachment of electrical contacts to the surface area of the rigid three-dimensional substrate and attachment and fixation of an electronic element.

EFFECT: application of this group of inventions will allow expanding the arsenal of technical means.
