• TITLE: USING STANDING WAVES IN PIEZOELECTRIC ARRAY
• AUTHOR(S): D. Kolev
• ABSTRACT: Resonance piezoelectric arrays have high sensitivity but the data acquisition can be split in two basic approaches – detection of the frequency shift or detection of the amplitude change. Both methods have their own advantages and disadvantages but for more fast data acquisition, it is preferable to use the amplitude method. The current article reviews the problems connected with the amplitude method of data acquisition and suggests some solutions to them.
