Abstract	While the usefulness of small scale prototypes for harvesting the energy of waves have already been demonstrated, the utilization of the capability of flow energy in rivers based on electroactive polymers is still a significant challenge. To harvest the energy of flowing waters, a novel flow energy converter based on a simple and environmentally sustainable mechanical design is developed, consisting of an elastomeric tube with a closing mechanism at the outlet side. Because the stationary stretch of the tube is comparably small, the tube has to be operated in resonance, which offers a high resonant magnification of the tube deformation. The resonant operation can be obtained, when the tube is closed rapidly and a shock wave is induced into the tube, which is often referred to as water hammer. Based on a small-scale prototype, this expected mechanical behavior of the tube was demonstrated.
