Abstract

Two possible designs are presented for the generation of electrical energy using the kinetic energy of flowing rivers. Both designs are connected with a turbulent flow or other hydrodynamic instabilities like a von Kármán's vortex street. The first is a fluttering flag made of a piezoelectric material, which follows the turbulence hence, bending periodically. Electrodes on the surface collect the generated charges. Secondly a microstructured piezo-bimorph is presented. It is connected with a paddle that also bends in a turbulent flow.
