Abstract
Ionic Polymer Metal Composites (IPMCs), as one of the most promising smart materials, can produce a large deformation for low voltage in the range of 0-5V. Since the materials were found, IPMCs have often been studied as actuators for their large deformation and inherent flexibility. Recently, IPMCs are applied to the optical lens-driving system. In this paper, we design miniature optical lens actuators for the focusing requirements. And two kinds of the driving structure, the petal-shaped and annular structure, are proposed. Then, the preparation processes of IPMCs and the actuators are presented and five kinds of petal-shaped and annular actuators are manufactured and their performances are tested, respectively. Finally, the performances of the actuators with different parameters are analyzed by an equivalent thermal model with FEA software.
