Abstract
Systems and methods for controlling vibrations of an ultrasonic handpiece generate an AC drive signal applied to a transducer of the ultrasonic handpiece to vibrate a tip of the ultrasonic handpiece. A property relating to a stiffness of tissue being contacted by the vibrating tip is determined based on a measured voltage and a measured current of the AC drive signal. A target displacement for the tip is determined based on the tissue property, and the AC drive signal is adjusted to achieve the determined target displacement.
