Abstract
Disclosed are a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to analyze the strength of a response signal transmitted from the wireless sensor in response to an excitation pulse generated by the reader device. In one embodiment, the reader device may be configured to engage be placed in a plurality of modes to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the wireless sensor to output a resonant signal. The reader device may receive the resonant signal from the wireless sensor and evaluate it against predetermined values. The evaluated signals may be used to assess the strength and the proximity of the reader device relative to the wireless sensor as it is implanted in a patient.
