Abstract

This work investigates the development and characterization of a bio-inspired swimmer actuated by Macro-Fiber Composite (MFC) piezoelectric laminates along with the required electronic hardware for untethered underwater operation. The main body of the swimmer is designed to imitate a trout-like streamlined geometry that has a 3Dprinted hard front enclosure and a soft tail portion. The focus is placed on the experimental characterization of the swimmer under various flow conditions and for various actuation frequencies. Straight swimming is explored in quiescent water, and further characterizations are performed in a water tunnel for different flow speeds.
