Abstract:
Systems and methods for sensing degradation of a piezoelectric actuator in a print head. One or more electrical pulses may be transmitted to the piezoelectric actuator that cause the piezoelectric actuator to bend, thereby creating a pressure wave. The pressure wave may be sensed and converted into an electrical signal. The electrical signal may be compared to a reference signal.
