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 going to be 3 actuators operated differentially in the 2-5Hz frequency range ~100-150VPP. Throwing in the added joys of microfluidics here, but thats just an added bonus
Any thoughts / logic around the below would be much appreciated!
- Power consumption / efficiency
- Deflection
- Hysteresis
- Noise
- Flow rate
- Cavitation
