FATIGUE-FREE BIPOLAR LOOP TREATMENT TO REDUCE IMPRINT EFFECT IN PIEZOELECTRIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18513918 titled 'FATIGUE-FREE BIPOLAR LOOP TREATMENT TO REDUCE IMPRINT EFFECT IN PIEZOELECTRIC DEVICE
Simplified Explanation
The present disclosure describes a method for optimizing the performance of a piezoelectric device by applying a first set of voltage pulses, monitoring a performance parameter, and selectively applying a second set of voltage pulses based on the deviation of the parameter from a reference value.
- The method involves applying a first set of voltage pulses to a piezoelectric device over a specified time period.
- During this time period, the method checks if a performance parameter deviates from a reference value by more than a predetermined amount.
- Depending on the deviation, a second set of voltage pulses is selectively applied to the device over a different time period, with variations in magnitude and/or polarity from the first set.

Original Abstract Submitted
In some embodiments, the present disclosure relates to a method in which a first set of one or more voltage pulses is applied to a piezoelectric device over a first time period. During the first time period, the method determines whether a performance parameter of the piezoelectric device has a first value that deviates from a reference value by more than a predetermined value. Based on whether the first value deviates from the reference value by more than the predetermined value, the method selectively applies a second set of one or more voltage pulses to the piezoelectric device over a second time period. The second time period is after the first time period and the second set of one or more voltage pulses differs in magnitude and/or polarity from the first set of one or more voltage pulses.
