Abstract :
In this article we used artificial sphincter utilising shape memory alloy (SMA) which consists of Ni and Ti. The anal canal is placed in between two boards fabricated from SMA. Because the form of SMA changes towards temperature, the flexure of the SMA boards in response to being heated by flexible heaters stuck on these boards effects opening anal canal.
