The discussion focuses on increasing the output current from a piezoelectric transducer using PZT ceramic, with a target of 1.2 Amps compared to the current output of 0.2 mA. Key strategies include using amplifiers and external power sources to amplify the signal, as well as connecting multiple transducers in parallel to enhance power generation. Additionally, the importance of energy flow and the relationship between voltage and current is emphasized, suggesting the use of transformers to achieve the desired current output through appropriate voltage reduction ratios.

A piezoelectric transducer "looks like a capacitor to the circuit trying to use it".Esfand Yar Ali said:How can I increase the output current from a piezoelectric trasnducer using PZT ceramic? The requirement is about 1.2 Amp but currently I'm only getting about 0.2 mA per unit.
You should be thinking in terms of energy flow = power. You do not specify the voltage generated or required, so I can't calculate power. What is the waveform and frequency of the physical stimulus?Esfand Yar Ali said:How can I increase the output current from a piezoelectric trasnducer using PZT ceramic?
