Abstract
This paper deals with finite element simulations of impedance characteristics piezoelecticelements utilized in sensors of acoustic emission (AE). Coefficients of piezoelectric material arechanged to evaluate the sensitivity to their variation in case they are not known precisely, so to whichextent can they influence the sensitivity of the sensor. Result showed sensitivity on coefficient inc-matrix, mainly to coefficients c11 and c13. Second investigated topic is issue with test stand for calibrationof AE sensors, where output of force sensor was affected by parasite signal. By contactlessmeasurement with laser interferometer was discovered the parasite signal is caused by mechanic ofthe system and it is no threat for the measuring chain.
