Development of an Active Micro Catheter using a Polymer Actuator

다국어 초록 (Multilingual Abstract)

Basic technologies to realize an active micro catheter using polypyrrole (PPy) as an actuator are being developed. The catheter is composed of a resin tube, a thin metal film for polymerization of PPy, and a PPy deposited on the electrode. From a finite element analysis, it was proved that a silicone tube with a diameter of 0.5mm and athickness of 0.05mm is the best for our specification. Copper film for electropolymerizing PPy, was deposited by RF sputtering on the silicone tube. The copper film was patterned by a laser machining. PPy was polymerized on the copper film, which was deposited on the half side of the silicone tube. When a voltage of 1.5V was applied to the PPy vs. a titanium electrode in a NaCl solution, the tube bent with a radius of curvature of 12cm.
