Shape Memory Alloy Actuated Ribbon Fin
I have always been fascinated by marine life. I remember going to the aquarium and being in awe of how gracefully these creatures glided through the water. This prompted me to study biomimetic aquatic propulsion. I spent a semester leading a team of four in the development of a shape memory actuator biomimitic ribbon fin. This fin consisted of five rays, each connected to a set artificial muscles. As the muscles bend, a sin wave propagates down the fin pushing water along with it generating forward motion. Our final version was capable of delivering roughly 0.06 N of thrust.
