PZT switching polarity at high voltages
Can someone please help me understand why my piezoelectric actuator switches polarity at a certain voltage? The below is just positive voltage applied across it, but ~50V it starts to deflect downwards instead of upwards. I understand that this is related to the coercive field and this is a...- loz88888888

Low frequency piezoelectric actuation optimization of waveform
Hi All - I am working on research around selecting the right waveform signal input for a piezoelectric micropump but can't seem to get a consensus on which waveform is most appropriate between trapezoidal or sinusoidal (assuming triangle & saw-tooth seem to be losers here). The application is...- loz88888888
