Performance characteristics of smart-materials based on lead zirconate titanate

This paper deals with the characterization of smart-material combinations based on the principle of phase transformation; that may provide drastic change in resistance with a small change in pressure. Lead zirconate titanate (PZT) has been selected as a base material for the development of smart-material combinations and pressure-sensitive devices were fabricated using the same. The devices have been characterized with change in pressure. Both dynamic and static pressures were used for characterization of the devices. Fast switching action i.e. large change in resistance with pressure has been observed and discussed. The reliability tests on the devices have also been performed to establish their long-term stability.
