PG - 169-77 LID - 10.1007/s10544-010-9482-6 [doi] AB - The present paper examined a novel micromachined column structured Ion Polymer Metal Composite (IPMC) actuator with multidirectional control capability. The developed 4-electrode transducer enclosed a section of optical fiber, thereby allowing electronic directional control of conducted laser light. The fabricated device with IPMC actuator dimensions of 5 mm x 2 mm x 1 mm reached a maximum displacement of 400 mum when a square wave of 9 V was applied to the top-bottom electrode pair. Displacements in different directions and moving angles were characterized with side-side and top-right electrode pairs connected to the actuating signals. Furthermore, the generating moment per volt per second by the transducer was analyzed. The maximum value of approximately 200 muN*m/V/s was displayed when the device actuated with the side-side electrode pair. Controlling the developed IPMC actuator moved the laser beam in multiple directions. This device could be promising for biomedical applications such as microendoscopic ocular surgery.
