Nonlinearity in the piezoelectric response limits the operating conditions of underwater transducers. In this work, the nonlinear effects are evaluated in terms of electrical current and induced strain as a function of drive level. Nonlinearity is further quantified within the active transduction material by evaluating the total harmonic distortion (THD) in the electromechanical response. Modified single crystals based on the binary lead magnesium niobate-lead titanate system were investigated. It is shown that single crystals show greater mechanical response and reduced THD, enabling operation at higher power levels. The performance of these single crystals is also compared to conventional high power lead zirconate titanate ceramics.

“…This mainly appears as generation of second and third harmonics (Aurelle et al, 1996). In order to show the influence of nonlinearities, the stiffness c m is assumed to be nonlinear and to have a restoring force to displacement characteristic of Duffing type, thus a cubic term multiplied by the factor b is added.…”

In this article, force and self-excitation driving methods for ultrasonic transducers are compared with each other in sense of their transient amplitude behavior in the presence of nonlinearities. An equivalent circuit transducer model is simplified to a series oscillator. The simplified model is averaged by the Van der Pol method in order to reduce the system at hand to its amplitude dynamics. The transient amplitude behavior of both driving methods is presented in an analytical form. At high vibration amplitudes, the system's natural frequency varies due to the nonlinear stiffness of the piezoelectric material and the vibration amplitude is likely to break down due to the jump phenomena. Therefore, the averaged models are extended by the nonlinear effects. From the amplitude behavior analysis of both systems, it follows that self-excitation is the preferable driving method in sense of obtaining a high operation bandwidth and a stable oscillation.

“…The current-jumping phenomena, 1)-3) the generation of higher harmonic voltages, 4), 5) the changes of observed material constants, 6), 7) and the rapid temperature rising of the devices 8), 9) are typical nonlinear phenomena. These phenomena are the main causes of the unstable operation and the increase of energy loss in high-power vibrations.…”

The nonlinear piezoelectric phenomena were investigated in PbTiO3-Pb(Sc1/2Nb1/2)O3 (PT-PSN) system ceramics, which is reported to be the ferroelectric relaxer material having a large d31 constant. The calculated values for current-jumping and resonance-frequency change obtained using our old simulation, in which only ξD31 is used as a nonlinear piezoelectric coefficient of third-higher term for the electrical field, agreed well with the measured values in the region of tetragonal phase. On the other hand, in the rhombohedral region, the calculated values did not agree with the measured values. This disagreement was resolved by reflecting the contribution of a new nonlinear piezoelectric coefficient of third-higher term for mechanical stress, ζD31, in the calculation. Furthermore, a nonlinear loss term was incorporated into the calculation by handing ξD31 as a complex number. The use of complex ξD31 enabled the exact prediction of the drop point of the current, which has never been possible.
