The target of this research is to develop a micro electric power generator for a low cost small river monitoring device. The power generator extracts an energy from flow of the river through the trailing vortex induced vibration (TVIV) occurred on a cruciform circular cylinder/strip-plate system. A prototype model for water flow was made and tested in high speed water tunnel. It was confirmed that TVIV occurs in water flow from 0.5 to 4 m/s. Power generation experiments were carried out in the water tunnel and the electric power was obtained in the same velocity range. The experiments show that this micro electric power generator is appropriate for a natural river of which flow velocity changes greatly. The power generator affects on TVIV as a damper. The obtained electric power was almost the same as a energy which was estimated from energy balance analysis, assuming the power generator is damper.
