Presentation of work ''High power electromechanical characterization of piezoceramics and low frequency ultrasound transducers by using algorithm for tracking changes in resonant frequency and electrical impedance'' at ICU 2015 conference

The team members presented work about using novel algorithm for tracking resonant frequencies of piezoceramic samples and ultrasound transducers at different driving and loading conditions at ICU 2015 Conference in Metz. The conference lasted from 10. May till 14. May. The paper was written by Antonio Petošić, Marko Horvat, Petar Mateljak and Marko Budimir. It was observed that losses at resonance of piezoceramic samples are significantly increased when excitation level is increased due to coupled nonlinear effects and temperature increase in the device under test.
