Systems and methods for detecting foreign object debris around a wireless power transfer system include a plurality of detectors, each detector featuring one or more loops of conducting material, and a controller configured to measure at least one of a voltage and a current in each detector and to determine, based on the measurements, whether foreign object debris is present around the wireless power transfer system, where at least some of the plurality of detectors include a first number of loops of the conducting material, and at least some of the plurality of detectors include a second number of loops of the conducting material larger than the first number.
