W pracy zamieszczono literaturowe informacje dotyczące piezoelektrycznych czujników ciśnienia typu PVDF, pozwalających mierzyć ciśnienie fali uderzeniowej o amplitudzie do 45 GPa z rozdzielczością czasową 5 ns. Zamieszczono formuły wzorcowania czujników. Opisano przykłady wykorzystania czujników w takich dziedzinach jak: kontrola ruchu drogowego, badanie właściwości materiałowych, pomiar ciśnienia fali uderzeniowej. Przedstawiono wyniki własnych pomiarów fal uderzeniowych wzbudzanych przez impuls promieniowania laserowego.

The review of publications on the subject of PVDF piezoelectric pressure gauges is presented in the paper. PVDF gauges allow to measure pressures up to 45 GPa with temporal resolution of about 5 ns. The calibration formulas of pressure gauges are included (fig. 1). Some examples of application of PVDF gauges in such areas like medicine, traffic control, material properties investigation and shockwave are presented. Results of author's measurements of laser induced shockwave are described (fig. 4 - 6). Influence of such parameters as sample thickness and acoustic impedance of layers on pressure profile is shown. The experimental setup will be used for optimization of laser shock processing technology.
