Figure 7
The displacement of two different two-piece trapezoidal piezoelectric bimorph beam which vibrates at its first resonance frequency. (a) The left subplot is the stationary displacement (without deformation) of the first design. (b) The right subplot is the stationary displacement (without deformation) of the second design. The shorter width W1 is 18 mm, and the longer width W2 is 40 mm for both two bimorph designs. The length of the beam L is 60 mm, the thickness of Tpiezo is 0.3 mm, and the thickness of the brass layer Ts is 0.05 mm.
