Abstract

This paper deals with the characterization of smart-material combinations based on the principle of domain polarization; that provides change in voltage with pressure. Different binary, ternary and quaternary material combinations have been studied from the point of view of phases present, Curie temperature and their ferroelectric nature. Lead lanthanum zirconate titanate (PLZT) material based devices were fabricated and characterized. A smooth change in output voltage with respect to small change in pressure has been observed and discussed. The reliability tests on the devices have been performed to examine their long-term stability..
