Cantilever beam oscillating ferroelectric generator

The invention relates to a cantilever beam oscillating ferroelectric generator. The current piezoelectric generator has low generating efficiency. And the invention comprises a metal cantilever beam, a mass block, a base, a ferroelectric film and an accumulator circuit. The base can oscillate up and down, one end of the strip metal cantilever beam is fixedly connected with the base and the other end thereof is fixedly connected with the mass block. The upper surface and the lower surface of the metal cantilever beam are respectively provided with the ferroelectric films in array, the top and the bottom of each ferroelectric film are provided with electricity collecting points in matrix, all collecting points on the top thereof are connected with top electrode wires by conductors, and all collecting points on the bottom thereof are connected with bottom electrode wires by the conductors. The top electrode wires are connected with one end input by the accumulator circuit, the bottom electrode wires are connected with the other end input by the accumulator circuit. Because the invention adopts the ferroelectric material as an electromechanical converter of the generator, susceptiveness is largely improved and larger output voltage and generation efficiency can be obtained.
