New approach for the QCM sensors characterization

• We describe a new method to characterize QCM.
• The developed method is carried out with traditional laboratory equipment.
• The approach brings similar performance than the methods with specific equipment that are more expensive.

The present work shows a novel approach for the QCM characterization. The method is based on the resonance principle of passive components. With the proposal, the QCM equivalent circuit parameters based on BVD (Butterworth-Van Dyke) model are obtained. The results achieved with this new technique are compared with specific commercial equipment usually employed for this purpose. The best advantages of the proposed method are its intuitivity and the possibility to obtain it with basic electronic equipment, usually present in any electronic laboratory.
