<p>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).
