Composites of lanthanum-doped lead zirconate titanate (PZT) (composition: Pb0.94La0.04Zr0.51Ti0.49O3) and silicone rubber were fabricated and their structural, dielectric and piezoelectric properties investigated. Studies on compositions with different amounts of PZT have revealed that the connectivity and the percentage of active PZT play a decisive role in determining the optimum value of conflicting properties such as the dielectric constant and the piezoelectric stress coefficient d33. A 50:50 PZT:silicone rubber composite turned out to be an optimum composition, with each phase self connected in three dimensions and with a high g33 coefficient about four to five times that of PZT.
