Method for optimizing a piezoelectric actuator, in particular for a phacoemulsification apparatus, through dynamic detection of its electromechanical characteristics and associated apparatus.

摘要

The invention relates to an optimization method for activating a piezoelectric actuator detection DYNAMICS OF ITS CHARACTERISTICS ELECTROMECANICAS, AND A DEVICE, INCLUDING A Phacoemulsificator based on this procedure, including the aforementioned piezoelectric actuator A piezoelectric transducer (1), DE TWO TERMINALS (1A) triggered by stress, said method being characterized FOR THE dETECTION OF ITS CHARACTERISTICS ELECTROMECANICAS, driving said transducer (1) cyclically SUSPENDED TO IDENTIFY THE PARAMETERS CHARACTERISTIC OF YOUR MOVE FREE FOR SCREENING PARAMETERS the signal generated by said transducer (1) ON THE eNDS OF TWO TERMINALS CITED (1A).
