碩士 === 國立中正大學 === 機械工程所 === 98 === This paper mainly utilizes micro-fabrication method to make three-dimensional (3D) four-electrode Ion Polymer Metal Composite (IPMC) actuator with accurate omnidirectional control capability, and enclose an optical fiber in the center of the device. By controlling the driving direction of the device to further control conducted laser light. This could be useful in applications such as microendoscopic ocular surgery. In this experiment, the size of the device is 1.2 mm × 1.5 mm × 7 mm. And we discuss if the lifetime of the device can be prolonged by parylene thin film coating. Besides, we construct the setup of measuring consuming current, and measure current and volts of the top-bottom electrode pair, side-side electrode pair, and top-side electrode pair through the device respectively, meanwhile we observe the displacement of the device, then compare the relationship among the three. Under the drive of operating frequency 0.1 Hz and volts 14 V, the displacement of the top-side electrode pair without optical fiber is 280 μm, and the one enclosed optical fiber is 200 μm. To prove the application of the device in microendoscopic ocular surgery, we make the laser light conduct into the optical fiber successfully, and let the laser light beam on an object represented as the eyeball. Finally, we improve the four-electrode IPMC actuator by designing two-dimensional (2D) clip shape on the front of the device, to increase the multifunction. Also, we test the clip force, which could be applied to the laser cure in varicosity and microendoscopic surgery.
