摘要

This invention relates to an optimization method for driving a piezoelectric actuator by dynamic detection of its electromechanical characteristics, as well as to a device, in particular a phacoemulsifier based thereupon, such piezoelectric actuator including a voltage driven, two-terminal (1a) piezoelectric transducer (1), said method being characterized in that, for detection of its electromechanical characteristics, the drive of said transducer (1) is cyclically discontinued in order to detect the characteristic parameters of its free motion by detection of the parameters of the signal generated by said transducer (1) at the ends of said two terminals (1 a).
