□ 기술개요Low profile piezoelectric linear actuator - Two piezoelectric transducers with a flexural vibration. - Piezoelectric transducer consists of piezoelectric ceramics and elastic plate. - Superposition of two flexural vibrations produced by the transducers with 90 degree phase difference. - The superposition creates an elliptic motion at the center tip of the actuator. - The elliptic motion produces a linear motion. - Size: 9×8×1 ㎣, 5×4×1 ㎣ - Velocity: 60∼80 mm/s, Force: 100∼200 g - Operating frequency: 90～100 kHz 2.기술 특징 - Simple structure and low profile. - Direct linear motion - No noise - High resolution (nm scale) 3.적용분야 - Actuator for Auto focusing, optical zoom, and image stabilizing of Camera module - Auto hinge for mobile phone - Micro actuator for industry
