| Zusammenfassung: | The present invention relates to a stacked piezoelectric element. The present invention, as an embodiment, proposes the stacked piezoelectric element comprising: a first piezoelectric body made of a piezoelectric ceramic sintered body; a second piezoelectric body made of the same piezoelectric ceramic sintered body as that of the first piezoelectric body; an adhesive layer formed to be interposed between the first piezoelectric body and the second piezoelectric body and coupling the first piezoelectric body and the second piezoelectric body; and an electrode formed on externally exposed surfaces of the first piezoelectric body and the second piezoelectric body. Therefore, the present invention is capable of increasing vibration displacement.
본 발명은 적층형 압전소자와 관련된다. 본 발명은 실시예로, 압전세라믹 소결체로 이루어지는 제1압전체, 상기 제1압전체와 동일한 압전세라믹 소결체로 이루어지는 제2압전체, 상기 제1압전체와 상기 제2압전체 사이에 개재되도록 형성되고 상기 제1압전체와 제2압전체를 결합시키는 접착층 및 상기 제1압전체와 상기 제2압전체에서 외부로 드러난 표면에 형성되는 전극을 포함하는 적층형 압전소자를 제시한다. |
