<p>An embodiment includes a radio frequency (RF) sensor system having a plurality of magnetoresistive (MR) sensors, where each MR sensor includes a configuration of MR elements and is adapted to produce a time-varying output voltage in response to a time-varying, external magnetic field. The RF sensor system also includes combiner circuitry, electrically coupled to the plurality of MR sensors, and adapted to receive and combine a plurality of time-varying output voltages from the plurality of MR sensors to generate a sensor output voltage. Another embodiment includes an electromagnetic sensor array having a plurality of MR sensors arranged in an array configuration, where each MR sensor includes a plurality of MR elements forming a Wheatstone bridge circuit, and where each MR sensor is adapted to produce a time-varying output voltage in response to a time-varying, external magnetic field. Still another embodiment includes a method for manufacturing an electromagnetic sensor array.</p> |
