a piezoelectric device
The strength and velocity of the shock wave were measured with piezoelectric pressure transducers that were flush mounted on the shock-tube walls.
Piezoelectric transducers are frequently used for the generation and detection of sound waves.
To account for mechanical, dielectric and piezoelectric losses, the material parameters are assumed to be complex.
The couple "membrane target" is driven by an input signal generated due to inverse piezoelectric effect.
A droplet extrusion system using either a thermal or a piezoelectric technique to eject sample droplets for analysis of chemical composition.
However, for frequencies typically considered in piezoelectric simulations the problem will remain indefinite.
Another challenging task we plan to deal with in the near future is the characterisation of hysteresis in piezoelectric systems by means of inverse methods.
A piezoelectric pressure transducer is flush mounted on the shock-tube wall near the end of the driven section.
