Abstract :
The static and dynamic characteristics of a slider incorporating a piezoelectric bender are presented. The behavior of the slider is simulated by a finite-element method that is used to evaluate the sensitivity, stresses, natural frequencies, and mode shapes of the slider. The analysis reveals the optimal thickness ratio and the dominant bending mechanism of the bender as well as the effect of the epoxy bond used in the fabrication process. Experimental data are also presented and show good agreement with the simulation results
