The invention relates to a flapping-wing micro aerial vehicle with renewable energy, and belongs to micro bionic aerial vehicles. A flapping-wing bionic support frame is connected with a motor and transmission mechanism, the motor and transmission mechanism and a control circuit module with an internal micro lithium battery are both fixed on a vehicle rack body, and a solar power generation film empennage is fixedly connected with the vehicle rack body; piezoelectric film flapping wings and solar power generation wing films are connected with a flapping-wing flexible wing frame which is located in the middle, the piezoelectric film flapping wings are located at the bottommost layer, the flapping-wing flexible wing frame is connected with the flapping-wing bionic support frame, and a power generation part is connected with the control circuit module through a wire. The flapping-wing micro aerial vehicle has the advantages that the structure is novel, optical energy can be converted into electric energy on the basis of a photoelectric effect of the solar films, an electricity charging and generating device made of the two materials is simple and has the advantages of being high in conversion efficiency, small in mass, wide in application range and the like.
