Measurement of polymer shear modulus using thickness shear acoustic waves

Interfacial behavior of immortalized hypothalamic mouse neurons detected by acoustic wave propagation

“…Under liquid loading conditions, Kanazawa and Gordon 19 have also derived models to explain how viscosity and density changes affect the resonant frequency and motional resistance. Studies have also been performed on coatings of elastic and viscoelastic films including Langmuir-Blodgett films, to monitor viscoelastic changes, 20 or polymer shear modulus, 21 with respect to changes in liquid properties. 22 Other biological systems commonly studied using the TSM sensor are nucleic acid hybridization, 23 protein conformational changes 24 and immunochemistry.…”

Using thickness-shear mode quartz resonator for characterizing the viscoelastic properties of PDMS during cross-linking, from the liquid to the solid state and at different temperatures

“…In chemistry, with a similar method, such a sensor can detect presence of harmful molecules in the air, acting as an electronic nose (Si et al, 2007). In mechanics, finally, it is used for measuring complex shear modulus of polymers (Lucklum et al, 2000;Holt et al, 2006;Serfaty et al, 2012) or for following its evolution during a specific process, such as dissolution (Hinsberg et al, 1986).…”

Comparison of experimental and numerical fatigue lives of rolling lobe air-springs for different diameters, inner pressures and temperatures

“…Because it is a rather simple sensor, it has since then been widely used in sensing applications in various domains, allowing us to determine with precision measurands such as mass density (Stockbridge 1966b), viscosity (Kanazawa and Gordon 1985) and pressure (Stockbridge 1966a), in a continuous and non-destructive manner, with sample as small as a microliter. In mechanics, for instance, it is used for measuring complex shear modulus ̃ in order to characterize a polymer (Holt, Gouws, and Zhen 2006) or follow its evolution during a specific process, such as dissolution (Hinsberg, Willson, and Kanazawa 1986). In biology, where its use continues to increase (Becker and Cooper 2011), the functionalization of the QCM surface with a definite substance allows to measure active species absorption or deposition, and then to recognize specific pathologies like schistosomiasis (Wang et al 2006) or Ebola fever .…”
