By combining this TGG method with low-temperature co-firing ceramics (LTCC) techniques, co-fired multilayer textured piezoelectric ceramic materials with inner electrodes were produced at a temperature as low as 925° C., which silver could be used. Trilayer PMN-PZT ceramics prepared by this method show a strain increase of 2.5 times, a driving voltage decrease of 3 times, and an equivalent piezoelectric coefficient (d*) improvement of 10 to 15 times that of conventional random ceramic counterparts. Further, a co-fired magnetostrictive/piezoelectric/magnetostrictive laminate structure with silver inner electrode was also synthesized. The integration of textured piezoelectric microstructure with the cost-effective low-temperature co-fired layered structure achieves strong magnetoelectric coupling. These new materials have promising applications including as actuators, ultrasonic transducers, and use in energy harvesters.application/pdfPatenthttp://pimg-fpiw.uspto.gov/fdd/76/244/102/0.pdf14376319C04B35/26C04B35/493C04B35/499C04B35/64C04B2235/3234C04B2235/3236C04B2235/3249C04B2235/3279C04B2235/3281C04B2235/3284C04B2235/787H01L41/20H01L41/0477H01L41/083H01L41/16H01L41/1875H01L41/273H01L41/4310224476
