Testing piezo-electric transducer

Title:
Testing piezo-electric transducer

Objective:

1. To test the output of piezoelectric.
2. To make the observation

Method:

1. Connect 4 pieces of piezoelectric in series and parallel connection and record the output.

Result:

In parallel connection, the piezoelectric will produce about 2-16V AC depends on the mechanical stress that had been apply towards. But the output voltage is stable because of the mechanical stress is not the in the same amount of pressure.
If in series connection, it will step up the the voltage up to 24V AC.

Conclusion:

.The piezoelectric will produce the AC output voltage when the mechanical stress is apply.
