Study on the Piezoelectric Transformer in the Bionic Active Member

Piezoelectric transformer is an important part in the bionic active member and it is an interactive electromechanical-coupled system. Piezoelectric intelligent structure models are presented from various angles and the effect of parameters of the piezoelectric coupled electromechanical system on the energy conversion efficiency of piezoelectric transformer is especially discussed in this paper. The establishment of the coupled model of the piezoelectric intelligent structure is helpful to interpret the physical essence of the bionic active member and to design the intelligent structure with better performance and higher efficiency.
