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.

This invention relates to a system of communicating with a radio frequency identification (RFID) transponder microchip (IC) for the purpose of accessing pre-programmed data. Such system involves direct electrical contact between the system reading the data from the memory in the transponder IC and the IC itself via two mechanical contact points. This system provides an interface with a transponder IC in order to energize the IC. Once the presence of the transponder IC is detected, the host system can read or write to and process preprogrammed data stored in the IC.

Method for detecting and communicating with RFID memory devices

The skin preparation device and sensor of the present invention include an array of rigid tines. The tines serve to 'self-prepare' the skin at each electrode site. These tines, when pressed against the skin, penetrate the stratum corneum, thereby reducing skin impedance and improving signal quality. A self-prepping device of the present invention is an optimized array of short non-conductive rigid tines in which the individual tines are created in a geometry that allows for a sharp point at the tip when molding, machining or etching is used as a method of fabrication.
