“…The typical signal acquired from a QCM-D circuit can be assumed to be the damped sinusoidal signal represented in (9) and shown in Figure 11. In order to evaluate the decay time constant τ, an exponential fit can be performed on the time sequence of the relative maxima of the signal in the time domain, V o (jT c ), j = t 0 T C + k f s T c , where [•] denotes the nearest integer.…”

“…In this context, it is evident how monitoring other quantities related to the resonant behavior of the quartz can be beneficial, as it provides additional information about the interaction with the target substance. This is usually attained by exploiting different measurement techniques, ranging from impedance analysis [6][7][8][9][10] to simpler and lower-cost ones such as those based on frequency measurement associated with dissipation monitoring [11][12][13][14][15][16], or on a variant of oscillator-based systems, called QCM-R, recently proposed to simultaneously obtain a measurement of the dissipative behavior of the quartz [17][18][19][20][21].…”

Quartz Crystal Microbalances (QCMs) are versatile sensors employed in various fields, from environmental monitoring to biomedical applications, owing mainly to their very high sensitivity. However, the assessment of their metrological performance, including the impact of conditioning circuits, digital processing algorithms, and working conditions, is a complex and novel area of study. The purpose of this work is to investigate and understand the measurement errors associated with different QCM measurement techniques, specifically focusing on the influence of conditioning electronic circuits. Through a tailored and novel experimental setup, two measurement architectures—a Quartz Crystal Microbalance with dissipation monitoring (QCM-D) system and an oscillator-based QCM-R system—were compared under the same mechanical load conditions. Through rigorous experimentation and signal processing techniques, the study elucidated the complexities of accurately assessing QCM parameters, especially in liquid environments and under large mechanical loads. The comparison between the two different techniques allows for highlighting the critical aspects of the measurement techniques. The experimental results were discussed and interpreted based on models allowing for a deep understanding of the measurement problems encountered with QCM-based measurement systems. The performance of the different techniques was derived, showing that while the QCM-D technique exhibited higher accuracy, the QCM-R technique offered greater precision with a simpler design. This research advances our understanding of QCM-based measurements, providing insights for designing robust measurement systems adaptable to diverse conditions, thus enhancing their effectiveness in various applications.

“…There is a rounded peak at both magnitude and phase curves. A rounded peak indicates a viscoelastic or elastic character, and the film dissipates some oscillation energy [28]. PANI film deposited at a scan rate of 30 mV/s also has a slightly curved phase peak and a peak magnitude that is not as sharp as other scan rates.…”

This work aims to determine how the scan rate affects PANI layers' morphology and resonance parameters deposited on quartz crystal microbalance (QCM). The PANI layer was produced using the electrodeposition method with a scan rate variation of 10 to 50 mV/s. The PANI layer deposited at a scan rate of 10 mV/s has an aggregate morphology, whereas the morphology becomes more scattered at a higher scan rate. On the other hand, the homogeneity of the distribution of PANI particles increases due to the increase in the scan rate. The QCM impedance profile also changes with PANI layer deposition at different scan rates. The QCM impedance profile with the PANI layer that is most similar to the uncoated QCM impedance profile is at a scan rate of 10, 40 and 50 mV/s. The resonance parameters, which represent the inertial mass and the dissipative characteristics of the PANI layer, were investigated. The PANI layer with the smallest resonance parameter has a scan rate of 10 and 40 mV/s. Therefore, the 2 scan rates are the best candidates to be applied further. HIGHLIGHTS The electrodeposition scan rate influences the morphology of the PANI layer deposited above QCM The amount of carbon distributed across the QCM surface represents how effective the PANI deposition was The resulting morphology will impact the PANI layer's impedance characteristic and resonance parameter values GRAPHICAL ABSTRACT

“…The modeling of interactions occurring at the QCM sensor surface as well as experimental methods [ 31 , 32 , 33 ] have undergone significant changes owing to the expansion of applications in liquid media [ 34 , 35 , 36 ]. The viscosity of the liquid also causes a change in the serial resonance frequency and damping factor; therefore, at least these parameters of the QCM sensor must be measured simultaneously.…”

To accurately model the effect of the load caused by a liquid medium as a function of its viscosity, the fractional order Butterworth–Van Dyke (BVD) model of the QCM sensor is proposed in this study. A comprehensive understanding of the fractional order BVD model followed by a simulation of situations commonly encountered in experimental investigations underpins the new QCM sensor approach. The Levenberg–Marquardt (LM) algorithm is used in two fitting steps to extract all parameters of the fractional order BVD model. The integer-order electrical parameters were determined in the first step and the fractional order parameters were extracted in the second step. A parametric investigation was performed in air, water, and glycerol–water solutions in ten-percent steps for the fractional order BVD model. This indicated a change in the behavior of the QCM sensor when it swapped from air to water, modeled by the fractional order BVD model, followed by a specific dependence with increasing viscosity of the glycerol–water solution. The effect of the liquid medium on the reactive motional circuit elements of the BVD model in terms of fractional order calculus (FOC) was experimentally demonstrated. The experimental results demonstrated the value of the fractional order BVD model for a better understanding of the interactions occurring at the QCM sensor surface.
