Broadband spike excitation method for in-liquid QCM sensors

A Quartz Crystal Microbalance (QCM) is a highly sensitive device based on the measurement of the resonance parameters of a thickness-shear piezoelectric resonator, which classical application is the detection of attached mass per unit area. Although the most economical ways of driving these sensors...
