- 초록
- The present disclosure relates to a piezoelectric device, and more particularly, to a piezoelectric device including: a piezoelectric actuator; a displacement transmission structure disposed on the piezoelectric actuator; and a displacement amplification structure disposed between the piezoelectric actuator and the displacement transmission structure. Here, the displacement amplification structure includes: a first displacement amplification structure and a second displacement amplification structure, which cross each other; and a fixing pin that passes through the first displacement amplification structure and the second displacement amplification structure to connect the first displacement amplification structure and the second displacement amplification structure. Also, each of one end of the first displacement amplification structure and one end of the second displacement amplification structure may be fixed on the piezoelectric actuator.
