Abstract

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.
