“…We also revealed the dramatic effect of the liquid shear viscosity and solid damping on the performance of the TPC sensor [44]. In order to reduce the shear viscosity effects, N. Mukhin et al [45] proposed a combination of a 1D and 2D phononic crystals approach for the excitation, detection, and confinement of a radial mode where both the excitation and the detection of the cavity mode are performed inside the cavity.…”

Acoustic Sensor Based on a Cylindrical Resonator for Monitoring a Liquid Flow

We present a numerical investigation of an acoustic sensor based on a cylindrical resonator to monitor the acoustic properties of liquids flowing in a tube. The sensor design consists of a hollow cylindrical washer surrounding the tube, which carries the liquid, and which can be filled during the sensing process. Due to the impedance mismatch between the liquid and the solid washer, we demonstrate the presence of high-quality factor resonances associated with the acoustic properties of the liquid (such as velocity, density, or viscosity) appearing as sharp spectral features in the transmission and detection measurements. An appropriate choice of geometrical parameters allows either to obtain two distinct resonances associated with the liquid and the surrounding washer or to overlap the narrow resonance of the liquid with the broad resonance of the washer and achieve a Fano-type resonance from their interaction. The sensitivity of the resonances to the acoustic properties of the liquid are investigated as a function of the geometrical parameters. We show that for highly viscous fluids, the vanishing of very narrow peaks can be avoided by increasing the thickness of the washer and, therefore, decreasing the quality factors. The calculations are performed in the framework of a finite element method. Our design provides a promising platform for sensing several acoustic characteristics of liquids flowing in tubes.

“…In recent years, there has been a growing interest in the applications of PnC sensors [18]. Compared with conventional quartz crystal microbalances (QCMs), PnC sensors can be designed with specific band structures and also have the potential for miniaturization and integration [19,20]. Current PnC based liquid sensors are mainly designed based on the defect modes constructed in the bandgaps [21][22][23][24].…”

We propose a reconfigurable phononic crystal (PnC) for detecting the concentration of solutes in liquids. The designed PnC consists of liquid-filled hollow pillars and connecting bars. The finite element method is used to calculate the transmission spectra and band structures of PnC filled with various liquids. We fabricate 3D printed samples and conduct corresponding experiments. The results show that sound velocity is the key parameter affecting the frequency of the passing band. As the sound velocity increases, the resonance frequency shifts down. For both NaCl solution and ethanol solution, good linear relationships between the resonance frequency and liquid concentration are established. Experimental results show good agreement with simulations, and stable detection capabilities are maintained in the presence of interference. The impact of fabrication tolerances on sensor performance has also been discussed, with a greater impact on sensitivity and a smaller impact on Q-factor. The reconfigurability also shows the potential of the design of multi-liquid PnC sensors.

“…Recently, we studied a tubular-type PnC, consisting of a periodic arrangement of cylindrical washers distributed along a tube [ 20 , 21 , 22 ] in which the liquid flows, for the purpose of sensing the physical properties of the liquid filling the tube. This design has the advantage of avoiding any perturbation of a flowing fluid by any element inside the tube, for instance, a periodic arrangement of its internal section.…”

We propose the design of a phononic crystal to sense the acoustic properties of a liquid that is constituted by an array of silicon ridges on a membrane. In contrast to other concepts, the ridges are immersed in the liquid. The introduction of a suitable cavity in the periodic array gives rise to a confined defect mode with high localization in the cavity region and strong solid–liquid interaction, which make it sensitive to the acoustic properties of the liquid. By using a finite element method simulation, we theoretically study the transmission and cavity excitation of an incident flexural wave of the membrane. The observation of the vibrations of this mode can be achieved either outside the area of the phononic crystal or just above the cavity. We discuss the existence of the resonant modes, as well as its quality factor and sensitivity to liquid properties as a function of the geometrical parameters. The performance of the proposed sensor has then been tested to detect the variation in NaI concentration in a NaI–water mixture.
