Measurement of the viscosity of liquid using a piezoelectric disk is described. Experiments with a radial expansion mode of a piezoceramic disk were carried out for water-glycerin mixture samples. Resonant resistance has linearity to the square root of the product of density and viscosity of a liquid around 113 kHz.
This paper describes the endurance of a ceramic hydrophone to measure high acoustic pressures at the focal point of Extracorporeal Shockwave Lithotripter (ESWL).
