Generating Performance Analysis on Incentive Environment of Rainbow Shape Piezoelectric Transducer
For improving rainbow shape piezoelectric transducer generating capacity under given dimension, aiming at external force and displacement incentive environment, relations between generating capacity and structural parameters and material properties of rainbow shape piezoelectric transducer were analyzed by simulation. The results show that on external force incentive environment, the output voltages of the rainbow transducer decrease as the width and initial curvature radius increase, the output voltages of the transducer increase as the length and elastic modulus ratio increase, the output voltages of the transducer have a maximum as the thickness ratio increases; on external displacement incentive environment, the output voltages of the transducer decrease as the thickness ratio and length and elastic modulus increase, the output voltages of the transducer increase as the initial curvature radius increases. Moreover, the output voltages of the inside piezoelectric film are larger than the outside piezoelectric film.
