dc.description.abstract	In the introductory part of the thesis, a brief explanation about the dynamic of bubble cavitation in homogenous and heterogeneous nucleation, pressure domain bubble growth and collapse. A review of methods used for the calibration of piezoelectric film sensors was elaborated to select the most appropriate method for the cavitation aggressiveness measurement. Regarding the sort pulse duration, the pencil-lead breaking method was selected. The test using the drop ball method was used performed for the comparison. To realize the calibration method an experimental assembly for the pencil-lead breaking method was designed and manufactured. Two kinds of sensors were tested using the pencil lead breaking method and the drop ball method. Pencil-lead breaking calibration two different hardness of 2mm pencil lead with two protruding lengths. The resulting constants are directly applicable to any measurements using tested PVDF films. The applicability of the pencil-lead breaking method was discussed resulting in the extension and modification of the experiment.	cs
