Title (EN) PIEZOELECTRIC ACTUATOR
(FR) ACTIONNEUR PIÉZOÉLECTRIQUE
(KO) 압전 액추에이터
Abstract:
(EN) The present invention relates to a piezoelectric actuator comprising: a fixing part; leg parts arranged in four directions with reference to the fixing part; and a tip part fastened to the end of each of the leg parts, wherein each of the leg parts comprises an elastic body and a piezoelectric body positioned on the elastic body. The present invention can provide a piezoelectric actuator drivable with a simple structure, and provides a simple driving principle for controlling the movement of the piezoelectric actuator, thus making it possible to easily control the piezoelectric actuator.
(FR) La présente invention concerne un actionneur piézoélectrique comprenant : une partie de fixation ; des parties formant un pied disposées dans quatre directions par rapport à la partie de fixation ; et une partie pointe fixée à l'extrémité de chacune des parties formant un pied, chacune des parties formant un pied comprend un corps élastique et un corps piézoélectrique positionné sur le corps élastique. La présente invention peut fournir un actionneur piézoélectrique pouvant être piloté au moyen d'une structure simple et fournit un principe de pilotage simple pour commander le mouvement de l'actionneur piézoélectrique, ce qui permet de commander facilement l'actionneur piézoélectrique.
(KO) 본 발명은 고정부; 상기 고정부를 기준으로 4 방향으로 배치되는 레그부; 및 상기 각각의 레그부의 끝단에 체결되는 팁부를 포함하고, 상기 레그부는 각각 탄성체 및 상기 탄성체 상에 위치하는 압전체로 구성되는 압전 액추에이터에 관한 것으로, 간단한 구조로 구동이 가능한 압전 액추에이터를 제공할 수 있으며, 또한, 상기 압전 액추에이터의 이동을 제어하기 위한 구동 원리가 간단하여, 상기 압전 액추에이터를 제어하는 것이 매우 용이하다.
