Abstract
A composite of PZT (Lead Zirconate Titanate) and a compliant polymer matrix aving 3-1 connectivity (i.e., in a diphasic material, one of the two phases is continuously self-connected in all three mutually perpendicular directions and the second phase is self-connected only along one of the three mutually perpendicular directions) and fabrication method thereof is described. An array of parallel PZT rod elements is embedded in a mechanically compliant polymer matrix with their axes along the direction of the poling electric field. Such a composite has a high value of g.sub.h, d.sub.h and g.sub.33 with very little sacrifice in the value of d.sub.33.
