1. A method for communicating data, comprising:
- receiving physiological data from a physiological sensor, the physiological data transmitted by a first transmission technique;
interrogating an RFID transponder using an RFID interrogator, wherein the interrogating causes the RFID transponder to transmit non-physiological data by a second transmission technique; and
receiving the non-physiological data using an RFID antenna coupled to an RFID antenna matching circuit.

Abstract
This invention relates to a physiological sensor which acquires pre-programmed data from an electrode or an electrode array using Radio Frequency Identification (RFID) technology. The source of the sensor may be authenticated by means of a wireless interface between an RFID transponder affixed to the electrode array, and an RFID interrogator embedded in the patient interface cable. The criteria for use are then verified to ensure that they are met by the electrode array before beginning signal acquisition. If the criteria are not met, a message is provided to the user via the monitor.
