摘要： The present invention relates to a method of manufacturing a piezoelectric ceramic body and devices therefrom. The method comprises mixing a piezoelectric ceramic powder with a polymer binder and surfactant to form a slip mixture, casting the slip mixture into a mold and setting to the slip mixture in the mold to form a green body, cutting the green body to form a cut green body with an array of micron-sized ceramic elements and separation, and sintering the cut green body to form a sintered ceramic body. The sintered ceramic body can be further process to encasing in a polymer material to form a piezoelectric ceramic-polymer composite. The piezoelectric ceramic-polymer composite can be further processed to form devices such as acoustic transducers and sensors.
