Nonlinear electromechanical response of the ferroelectret ultrasonic transducers
Original language description
The ultrasonic transmission between two aircoupled polypropylene (PP) ferroelectret (FE) transducers in dependence on the amplitude of the high-voltage exciting pulse revealed a strongly nonlinear electromechanical response of the FE transmitter. This phenomenon is described by a linear increase of the inverse electromechanical transducer constant of the PP FE film with an increase of the exciting electrical pulse amplitude (by a factor of 4). The electrostriction contribution can be attributed to the electrostatic force between electrodes and the Maxwell stress effect. A significant enhancement of the ACUS system transmission (12 dB) and signal-to-noise ratio (32 dB) was demonstrated by the increase of excitation voltage up to 3500 V.
