  • PIEZOELECTRIC-DRIVING OPTICAL LENS
    Publication number: 20100073787
    Abstract: A piezoelectric-driving optical lens is disclosed, which comprises: a lens, having a barrel with a friction ring annularly mounted on the outer wall of the barrel as the outer diameter of the friction ring is larger than that of the barrel; a plurality of piezoelectric stators, arranged surrounding the lens and abutted against the friction ring, for providing a rotation driving force to the lens for focusing or zooming function; and a seat, for receiving the lens and the plural piezoelectric stators; wherein, the plural piezoelectric stators can actuate simultaneously to output a maximum driving torque.
    Type: Application
    Filed: December 2, 2009
    Publication date: March 25, 2010
    Applicant: Industrial Technology Research Institute
    Inventors: HAN-WEI SU, CHAO-CHANG HU, SHENG-CHIH SHEN, JWO-MING JOU, KAI-LIN HUANG
