“…However, they are also more complex because they involve the functionalization of the electrode in the crystal in order to detect a specific protein related to the disease. There are also studies that relate similar piezoelectric techniques to sense the viscosity of biological samples, such as: the use of cantilevers [22,23,24]. Sensors based on cantilevers are also valid to obtain the viscosity values in biological samples; the physics principle is the same.…”

The main objective of this article is to demonstrate through experimental means the capacity of the quartz crystal resonator (QCR) to characterize biological samples of aqueous dilutions of hyaluronic acid according to their viscosity and how this capacity may be useful in the potential diagnosis of arthritic diseases. The synovial fluid is viscous due to the presence of hyaluronic acid, synthesized by synovial lining cells (type B), and secreted into the synovial fluid thus making the fluid viscous. In consequence, aqueous dilutions of hyaluronic acid may be used as samples to emulate the synovial fluid. Due to the viscoelastic and pseudo-plastic behavior of hyaluronic acid, it is necessary to use the Rouse model in order to obtain viscosity values comparable with viscometer measures. A Fungilab viscometer (rheometer) was used to obtain reference measures of the viscosity in each sample in order to compare them with the QCR prototype measures.

“…As given in Eq. (8) in theoretical model, the resonant frequency is significantly affected by the density and product of density and viscosity. Therefore, it is clearly visible that the resonant frequency shift is higher in group I liquids compared to the group II liquids.…”

“…Hence by tracking the resonant frequency and the quality factor (which are coupled each other) from the dynamic behavior of cantilever sensor immersed in liquid, the density and viscosity can be determined [4]. Several studies have been done to simultaneously measure the viscosity and density by relating quality factor changes with viscosity and resonant frequency shift with density [2,[4][5][6][7][8][9]. At present, several theoretical models are available for the calculation of viscosity and density from the frequency response of cantilever sensor to separate the dissipative and inertial effects of viscosity and density in liquids.…”

“…The resonant device based on micro-electromechanical systems (MEMS) technology has been employed in widespread applications for determining chemical and physical properties in liquid media. For decades, the dynamic-mode cantilevers have received extensive attention for decades, such as in density and viscosity monitoring [1][2][3][4], the material imaging by AFM (atomic force microscope) [5], and the biochemical active molecule and particle detection [6][7][8]. In order to make the most beneficially use of their capabilities of simplicity, reliability, high sensitivity, and mature fabrication process, diverse cantilevers were designed with different structural shapes [9,10], actuation and sensing methods [11][12][13], and vibration modes [14,15].…”

This study investigates the sensing characteristics of micromachined electromagnetic cantilevers vibrating at different resonance orders and under static or flowing liquid immersions. The cantilever is designed with a wide-plate structure, which contributes to the modal optimization for basic and higher-order torsions. The fluid-structure interaction is used to analyze the parameterized expressions of the density and its changing sensitivity based on the cantilever's flexural and torsional vibrations. They have successfully clarified the comprehensive factors that influence the density measurement performance. The study shows that the analytical predictions for the density changing sensitivity agree well with the experimental results. The experiments prove that the cantilever under flowing immersion appears significantly degraded in its density measurement accuracy. Higher mode and shorter length enable the cantilever to respond better density sensing behaviors under flowing immersion. These results here can be further generalized to guide the optimal design of cantilever-based resonators in flowing liquid monitoring.
