    • The present invention is a technology for forming a ceramic thick layer on a polymer substrate by using a room temperature injection process. Generally to form the ceramic thick layer on a polymer substrate by using the room temperature injection process, layer deposition is performed by a method using plate-type particles to make a strong anchoring with a basic material. But, there are problems that a bonding force is not enough, a ceramic layer deposited through strong collisions has crystalline grains of nanosizes. The present invention is to provide the technology for forming the ceramic thick layer on the polymer substrate with adhesive properties by using the room temperature injection process. The size of the crystalline grains in the deposited ceramic layer is nearly equal to the size of initial raw powder, hundreds of nanometers to tens of nanometers. When a piezoelectric ceramic thick layer is formed on the polymer layer according to the present invention, the piezoelectric ceramic thick layer is applicable to a flexible piezoelectric device (example: a flexible piezoelectric harvester, a sensor).

    • 本发明是通过使用室温注射法在聚合物基材上形成陶瓷厚层的技术。 通常,通过使用室温注射法在聚合物基材上形成陶瓷厚层,通过使用平板型颗粒的方法进行层沉积,以用碱性材料进行牢固的锚固。 但是,存在接合力不足的问题,通过强烈的碰撞沉积的陶瓷层具有纳米尺寸的晶粒。 本发明是通过使用室温注射法提供在具有粘合性的聚合物基材上形成陶瓷厚层的技术。 沉积的陶瓷层中的晶粒尺寸几乎等于初始原料粉末的尺寸,几百纳米到几十纳米。 当在根据本发明的聚合物层上形成压电陶瓷厚层时,压电陶瓷厚层可应用于柔性压电装置(例如,柔性压电收割机,传感器)。 (标号)(AA)极化方向
