　　對於泌尿系統疾病的患者，例如神經受損，外傷意外傷害或者孕婦懷孕過後，導致身體無法自主控制尿道收縮的情形，此時可能會利用尿道人工括約肌來幫助尿道收縮。本研究對於尿道人工括約肌(AUS)提出一個新的設計，有別於液壓式尿道人工括約肌，本研究使用彈性銬形環以及高分子材料來收縮及舒張尿道，控制尿道的排尿動作。先利用彈性銬形環如聚二甲基系氧烷矽膠(Polydimethylsiloxane, PDMS)將尿道閉鎖，到需要排尿時，將離子性聚合物-金屬複合材料(ionomeric polymer-metal composite, IPMC)通以直流電源致動來撐開彈性銬形環，使尿液能夠釋放，直到完成排尿，複材停止致動，使彈性銬形環利用本身恢復彈性來束縛住尿道，整個系統利用低於0.5安培之直流電源來控制元件的致動，並且靠控制器來達到功能需求。

　When the urinary system is injured, due to nerve damaged, accident or pregnancy, it will result in urinary incontinence. The symptom may be remedied by artificial urethral sphincter (AUS). In this thesis a new AUS was developed which is different from the commercial hydraulic type design. The new design is consisted of a cuff made of elastic material PDMS (Polydimethylsiloxane) and an actuating film made of IPMC (Ionomeric polymer-metal composite). The system can be utilized to control the contraction and expansion of urethral. By contraction of the elastic material, urethra can hold urine from leaking and the IPMC film can open the elastic cuff by applied voltage when releasing the urine. After urinating, the IPMC will stop actuating and the elastic cuff will return to its normal close state by its own elasticity. The new system is actuated by direct current with magnitude less than 0.5 amperes, and the desired function can be achieved by using a feedback controller.
