摘要：A piezoelectric sensor for mass detection is a new type of sensor using
   piezoelectric materials as transverse transducer.A piezoelectric sensors
   resonance frequency shift is measured to quantify the small mass
   attached to the surface.Since the adsorbed mass is very small,the
   testing accuracy of the piezoelectric sensor is strongly depended on the
   mass detection sensitivity which is defined as the resonance frequency
   shift with respect to a loaded mass.This paper presents an investigation
   into the derivation of the relationship between the mass detection
   sensitivity and the structural configuration parameters.The dependence
   of mass detection sensitivity on structural configuration parameters and
   resonance modes is examined through numerical examples.
