The influence of interphase and matrix stiffness on the sensitivity of 1 - 3 piezocomposites is investigated. An analytical model is first developed to predict the static out-of-plane displacements of a single piezoelectric rod composite. The model accounts for the transversely isotropic nature of the ceramic rod and the presence of an interphase region with different properties from the surrounding matrix. Laser interferometry was then utilized to measure displacement profiles for samples consisting of a single PZT-5H rod embedded in Spurr epoxy. Three different interphase conditions were considered. Both the experimental measurements and theoretical predictions demonstrated that changes in the interphase modulus had a significant effect on the maximum displacement on the rod. Rod displacement and sensitivity decreased with increasing interphase stiffness.
