Analyte sensor

An analyte monitoring system, the system comprising:

• an electrochemical sensor configured to measure a level of an analyte in a biological sample from a patient, wherein the biological sample is a tear, wherein the sensor is configured to be fastened to a portion of a patient's body, wherein the sensor is configured to be powered by inductive coupling, wherein the sensor comprises:
• a first wire comprising a working electrode configured to generate a signal indicative of an analyte concentration;
• a second wire comprising a reference electrode;
• and
• a third wire comprising a counter electrode;
• and
• sensor electronics configured to operatively connect to the sensor, wherein the sensor electronics are configured to process data obtained from the sensor.
