Latest Patents

One of his latest patents is a method for manufacturing flexible laminated piezoelectric composites. This method involves wet-mixing ceramic powder, a polymer binder, a plasticizer, and a solvent for 4 to 72 hours to create a mixed slurry. The mixed slurry is then introduced into a tape casting process to prepare multiple piezoelectric composite sheets. These sheets undergo drying and forming using a roll-to-roll process, followed by the formation of internal electrodes. The final steps include laminating and pressing the sheets to generate a piezoelectric composite sheet laminate, which is then cut into the desired shape and size.

Another notable patent is for a stack-type piezoelectric element and piezoelectric actuator. This invention features a stack-type piezoelectric element with a reduced capacitance value while maintaining the displacement amount. The element includes a piezoelectric layer made from a piezoelectric material, along with electrode layers that contain at least one internal electrode layer formed inside the piezoelectric layer. The internal electrode layer consists of multiple split electrodes arranged in a longitudinal direction, enhancing the functionality of the piezoelectric actuator.
