It was tested to what extend torsional acoustic resonators can serve to in vivo differentiate between healthy and tumorous brain tissue. The resonators employed consist of crystalline quartz. They are cylindrically shaped. The resonance frequency at

The effects of a finite polarizability of a liquid sample onto the series resonance frequency of a piezoelectric resonator are described within the small-load approximation. It is found that the sample's electrical capacitance (the ratio of surface p

A quartz crystal microbalance (QCM) is described, which is based on a torsional resonator, rather than a conventional thickness-shear resonator. Typical applications are measurements of film thickness in the coating industry and monitoring of biofoul

The work describes the use of readily available and economical quartz crystal torsional resonators for microweighing. The resonance behavior was probed by impedance analysis. Torsional resonators are straightforwardly adapted to the detection electro
