There are actually several ways to approach the problem, but running two actuators inside the same preload cage is not one of them as this would produce something other than a single resonance. The simplest and most effective is to use a PLL tuning circuit like that found in this small generator Ma...

I think you misunderstand about there being 2 "sets". There is really only one set. The stack acts as a single unit. The divisions in the stack are there for two purposes. First, many thin layers of PZT are used instead of a single layer to keep the voltage requirements down. It's easier to run wit...

Both the power into the stack needs to be on resonance and the acoustic action of the stack needs to be on resonance. . I read the recent Fearn & Woodward AIAA paper and it states that the electrical and mechanical resonant frequencies don't necessarily coincide and can vary by 1-2kHz. Also when th...
