US 11,852,899 B2 · Ultrasound emitting contact lens

Abstract

A contact lens for application to a human eyeball capable of emitting ultrasonic pressure waves from a plurality of piezoelectric transducers to mitigate the effects of airborne eye irritants and infectious microorganisms. The piezoelectric transducers converts mechanical energy applied upon the contact lens from the eyelid as the eyelid blinks and/or winks into electrical energy to be used for emitting ultrasonic pressure waves from the piezoelectric transducers. The ultrasonic pressure waves destroy airborne microorganisms near the contact lens. A photodiode onboard the contact lens indicates when the eyelid is not closed in order to limit or prevent emission of ultrasonic pressure waves from the piezoelectric transducers while the eyelid is closed. An antenna onboard the contact lens receives information from augmented reality glasses or other computing devices.

Dependent claims

An ultrasonic emitting electronic contact lens apparatus placed on an eyeball comprising:

a translucent lens portion having a concave surface and a convex surface;
and
a plurality of piezoelectric transducer portions embedded upon the convex surface, where the plurality of piezoelectric transducer portions are arranged along the outer circumference of the convex surface, and the plurality of piezoelectric transducer portions emit ultrasonic pressure waves, wherein the plurality of piezoelectric transducer portions emit ultrasonic pressure waves away from the eyeball and are configured to remove one or more microparticles from air in front of the contact lens.

A computer system (CS) for use with a contact lens placed on an eyeball, with the contact lens including a plurality of piezoelectric transducers, the CS comprising:

a processor(s) set;
a contact lens placed on the eyeball, the contact lens having a plurality of piezoelectric transducers;
a set of storage device(s);
and
computer code stored collectively in the set of storage device(s), with the computer code including data and instructions to cause the processor(s) set to perform at least the following operations:
responsive to a blinking motion of an eyelid over the eyeball, converting pressure from the blinking motion of the eyelid applied to the piezoelectric transducers into electrical energy;
emitting, using the converted electrical energy, ultrasonic pressure waves through the piezoelectric transducers;
and
removing one or more microparticles from air in front of the contact lens using the ultrasonic pressure waves emitted through the piezoelectric transducers away from the eyeball.
