Bio-inspired Engineering about Fish Fins

Professor Qiang Zhu

The fins of a fish are often strengthened by embedded rays, and therefore possess anisotropic flexibility. Tendons and muscles attached to these rays also allow the fish to actively control the motion and deformation of its fins. This design greatly enhances the efficiency of fish locomotion. Dr. Zhu is concentrating on numerical characterization of the structure versus function of these bio-structures. The eventual application will be bio-inspired propulsion systems.
