Latest Patents

One of Itakura's latest patents is for a multilayer piezoelectric device. This device comprises a multilayer body and first and second outer electrodes. The multilayer body includes base, first and second driving parts, and a non-driving part. The driving parts and non-driving part extend from the base along the stacking direction. The first driving part is positioned closer to the non-driving part than the second driving part. Each driving part features first and second inner electrodes that oppose each other in the stacking direction. The base has a third inner electrode that extends along a plane orthogonal to the stacking direction. The first outer electrode connects to the first inner electrode, while the second outer electrode connects to the second and third inner electrodes. Notably, in the stacking direction, the overlap area of the third and second inner electrode of the first driving part is greater than that of the second driving part.

Another significant patent by Itakura is for a laminated piezoelectric element and its production method. This element is capable of being sintered at low temperatures while exhibiting high piezoelectric properties. It comprises multiple piezoelectric layers, each made from a composite oxide as the main constituent, along with several internal electrode layers formed between the piezoelectric layers and containing silver. The piezoelectric layers consist of a sintered body represented by a specific formula, ensuring optimal performance.
