Polymer based thickness shear mode acoustic resonator for sensing of fluid complex shear modulus
This paper describes a low-cost high-quality acoustic device for measuring complex shear modulus of contact fluid. The sensor is based on thickness shear mode (TSM) piezoelectric resonator. It consists of stretched and poled polyvinylidene fluoride (PVDF) films utilizing the shear piezoelectric properties of PVDF. The resonant frequency and quality factor of a 1 mm thick sensor in air is measured to be respectively, 590 kHz and 140. Experiments demonstrate that the sensor can effectively measure the change of complex shear modulus with a sensitivity of 0.035 kHz/Pa and detection limit of 108 Pa over 50–900 Pa range.
