Design and testing of an SMA-actuated fin for bioinspired soft robots
The thesis consists of designing a fin inspired by the cownose ray, entirely made of silicone rubber, without any rigid mechanism inside, and actuated by SMA (Shape Memory Alloy) coils. The lack of rigid elements inside the fin helps reproduce better the natural movement of these fishes, and arranging the coils in pairs, they work

Study of the propulsive performance of fins
The most common propulsive strategy of fishes and cetaceans is the Body-Caudal fin movement in which the animal undulates or oscillates its body, pushing backward the surrounding water. Most of the thrust is generated by the movement of the caudal fin, and every fish has a peculiar fin shape with a particular motion law, which
