Examples of multimodal transduction approaches for the gas sensor development: (A) a single chip microsystem for smart gas sensing simultaneously using mass sensitive calorimetric and capacitive measurements, (B) a sensor design utilizing QCM and the field effect transistor (FET) approach, and (C) and integrated electrochemical QCM for simultaneous EIS and mass sensing measurements.
