The temperature influence on the piezoelectric transducer noise, measurements and modeling
In many case, the SNR limit the performance of a transducer. The understanding of the nature and the behavior of the noise allow to increase this SNR. First, we present the noise and impedance real part measurement results in air and in water. We show the link between them. The second part is a temperature study which confirms this influence. We show the little evolution of the total output noise in a conditioning chain. Finally, we use a derivate of Redwood electro-acoustical model to estimate the noise. The measurement results agreed with this one.
