  • Abstract
    A number of Pb(Mg1/3Nb2/3)O3-based materials were characterized to determine the effects of temperature on their induced strain and hysteresis properties. Simultaneous determination of the transverse and longitudinal properties allows the calculation of both an effective Poisson ratio and an effective hydrostatic d coefficient. One composition showed significant variation in the effective Poisson ratio (0.28 to 0.40) across the temperature interval 0 to 40°C. The large, effective hydrostatic coefficients (up to 300 pC/N), combined with the high permittivity of the materials, indicate that these materials have potential for use as high-sensitivity hydrostatic sensors
