The substrates in Trapezoidal Bridge piezoelectric transducer will shield most of the stress, causing unutilised low stress regions of PZT and lower power output. Thus, this paper presents an improved optimisation scheme by optimising the overall stress distribution of the PZT with the considerations of suitable loading forces and optimised dimensions of amplifier structure. The developed Finite Element Model had been validated experimentally. It is found that the thickness of end cap and substrates are the important parameters in optimising the PZT transducer. The overall PZT's stress level has been enhanced with a much closer stress distribution to its threshold.
