Piezoelectric ceramic application and collection of electrical signals

1. Piezoelectric ceramic micro-displacers and piezoelectric ceramic drivers, are they substantially different?

Piezoelectric ceramic microdisplacers and piezoelectric ceramic actuators are essentially indistinguishable because their core components are piezoelectric ceramics. However, the method of use is different. A piezoelectric ceramic micro-displacer that uses a piezoelectric effect to convert a micro-displacement into an electrical signal for output. In the piezoelectric ceramic driver, the electrical signal of piezoelectric discs crystal is converted into an acoustic signal to be output.

2. Piezoelectric ceramics collect electricity and supply power to the LED. Can this be achieved?

If this is the case, it is very difficult to carry out the actual operation, and it is not easy to implement. Because piezo ceramic plate transducers have large voltages and large currents, and their discharge time is short, they are not easy to implement. Further, if a plurality of piezoelectric ceramics are connected in parallel, although the current can satisfy the requirements, the voltage is too large, so that it is not.

3. How should the electrical signals generated by piezoelectric ceramics be collected?

The electrical signal generated on the piezoelectric ceramic wedge, if you want to collect it, then you need to use the data acquisition card, which is the AD card. In the specific operation, it is amplified and collected within the range of the required input signal, but it is generally digital for computer processing. However, it can also be displayed directly through an oscilloscope, which is more intuitive.
