METHOD OF SENSING DEGRADATION OF PIEZOELECTRIC ACTUATORS |
| 摘要 |
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. |

1. A method for sensing degradation of a piezoelectric actuator in a print head, comprising:
transmitting one or more electrical pulses to the piezoelectric actuator, wherein the one or more electrical pulses cause the piezoelectric actuator to bend, thereby creating a pressure wave; sensing the pressure wave; converting the pressure wave to an electrical signal; and comparing the electrical signal to a reference signal. |
