    Increasing Energy-harvesting ability of piezoelectric unimorph cantilevers using Spring Supports

    We fabricated a spring-supported piezoelectric unimorph cantilever (SPUC) with enhanced energy-harvesting characteristics by using a 0.69Pb(Zr0.47Ti0.53)O3–0.31Pb(Ni0.6Zn0.4)1/3Nb2/3)O3 + CuO (0.5 mol%) thick fil...

    Positive temperature coefficient of resistance effect in Na2Ti6O13-doped 0.94BaTiO3–0.06(Bi0.5Na0.5)TiO3 ceramics

    The positive temperature coefficient of resistance (PTCR) characteristics of Na2Ti6O13 (NT)-doped 0.94BaTiO3–0.06(Bi0.5Na0.5)TiO3 (BBNT) ceramics were investigated in order to evaluate the effect of NT as a new a...
