Exempel på piezoelectric

• 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.

• Piezoelectric current from shunted and shorted guard-ring quartz gauges.

• In this paper we deal with a mathematical model which describes the frictional contact between a piezoelectric body and a foundation.

• The measuring volume is formed in the far field of intersecting highly directional piezoelectric transducers.

• A piezoelectric swimming microrobot is described, with industrial applications in pipelines and also with medical ones in, for example, blood vessels.

• One of the beads is held in an optical trap while the other is held on a micropipette mounted on a piezoelectric flexure stage.

• A waveform generator sent a sinusoidal voltage to the piezoelectric transducer through an amplifier.

• Depending on the sound source, one can differentiate between electrohydraulic, electromagnetic, and piezoelectric systems.
