1. A system, comprising:
- an interrogation component that is configured to;
transmit an interrogation signal to a contact lens, wherein at least one surface wave acoustic based sensing component is disposed on or within the contact lens; and
receive a reflected portion of the interrogation signal from the contact lens, wherein the reflected portion of the interrogation signal is indicative of eyelid location relative to the at least one surface wave acoustic based sensing component; and
a detection component configured to determine or infer a location of an eyelid relative to the at least one surface wave acoustic based sensing component based upon at least a signal strength of the reflected portion of the interrogation signal.

15. A non-transitory computer-readable medium having instructions stored thereon that, in response to execution, cause at least one device including a processor to perform operations comprising:
-
transmitting an interrogation signal to a contact lens, wherein at least one surface wave acoustic based sensing component is disposed on or within the contact lens; receiving a reflected portion of the interrogation signal from the contact lens, wherein the reflected portion of the interrogation signal is indicative of eyelid location relative to the at least one surface wave acoustic based sensing component; and inferring a location of an eyelid relative to the at least one surface wave acoustic based sensing component based upon at least a signal strength of the reflected portion of the interrogation signal. - View Dependent Claims (16, 17)
