摘要

Piezoelectric resonators have been in use as mass-sensing devices for almost half a century.More recently it was recognized that shifts in frequency and bandwidth can come about by a diverse variety of interactions with the sample.The classical"load"consists of a thin film,which shifts the resonance frequency due to its inertia.Other types of loading include semi-infinite viscoelastic media,rough objects contacting the crystal via isolated asperities,mechanically nonlinear contacts,and dielectric films.All these interactions can be analyzed within the small-load approximation.The small-load approximation provides a unified frame for interpretation and thereby opens the way to new applications of the QCM.
