MULTISIM- simulation process for the resonant frequency measurement of quartz crystal microbalance

Abstract

A piezoelectric transducer such as the quartz crystal microbalance (QCM) oscillating at resonance was used to shake the bound particles free from the surface. A novel approach of generating multi-sinusoidal waves was proposed for measurement of QCM resonant frequency, in order to drive QCM at resonance for bond-rupture biosensing applications. It reveals MULTISIM simulation processing can much effectively determine QCM resonant frequency by an impedance-frequency profile.
