    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...

    Low frequency piezoelectric actuation optimization of waveform

    Thank you sir! Yes totally agree and after I sent it realized it was way too general lol Get that from a high level, maybe i will try some more specific questions. And please feel free to just direct me to sources of info as not looking for spoon feeding, just can't seem to find definitive...

    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...
