Popis: The frequency response of 5 and 6 MHz AT‐cut electrochemical quartz‐crystal microbalances to the highly nonuniform distribution of mass loading appearing in localized corrosion or local deposition was investigated. It was shown that the evolution of the frequency deviates from the theoretical one calculated using the conventional sensitivity. This behavior is described in terms of localization of resonance modes under the heavy loaded part of crystal. Mass‐dependent corrections to the conventional sensitivity were calculated.
