Displacement sensing properties and sensitivity of a piezoelectric bimorph are investigated based on the probabilistic design technology（PDT） included in ANSYS software. The relationships between the sensitivity and the piezoelectric material constants, geometrical dimensions of the piezoelectric bimorph are carried out in detail. The analyzed results would give some important instructions to the design and optimization of the piezoelectric bimorph sensors for the practical applications.
