The electromagnetic induction energy conversion unit 32 includes a pair of magnet units 321 arranged to face each other and an advance / retreat unit 322 that moves forward and backward like a pendulum between the magnet units 321. In addition, the magnet part 321 on the near side of the drawing is represented by a broken line for convenience of explanation. By the way, since the turntable X itself is heavy, it rotates following a slow change in the wind direction, but hardly moves against high-frequency motions of fluttering. The energy converter A4 is arranged so that the surface portion 101a of the flexible flat body 101 is substantially parallel to the wind direction, as in the above-described embodiments.

The lower end side of the piezoelectric bimorph element 3 a is supported by the base 9, while the upper end side is attached to the flagpole 2. In the present embodiment, the direction in which the piezoelectric bimorph element 3a of the lower end side piezoelectric energy conversion unit 31 can be displaced (arrow D1) and the direction in which the surface portion 1a of the flexible flat body 1 faces substantially coincide. In some cases, the tag chip attached to the product in the package cannot be brought close to the product, and requires a larger amount of power.
However, in the former configuration, when the wind is weak, the blades do not rotate and cannot generate power. The part that receives the wind, such as a generator that uses the vibration excited in the vertical direction, is applied to the flexible gap that is guided in the gap between the guide plates and tensioned to the flexible cloth. First, the energy converter A is arranged so that the surface portion 1a of the flexible flat body 1 is substantially parallel to the wind direction, in other words, the horizontal rail 6 is substantially parallel to the wind direction. In each of the above-described embodiments, the flexible flat body 1 is arranged at a position exposed to the wind.

The vibration that absorbs energy such as the pressure of the fluid applied to the flexible flat body is excited regardless of the flow velocity. In this embodiment, the base 9 includes a rotation support portion 91 that rotatably supports the rotary table X. Although the wind direction of natural wind changes, the force of the flexible flat body 1 includes a low-frequency component that follows the wind direction as well as a vibration component with respect to the piezoelectric energy converter 30 on the upper end side. Then, as in the first embodiment, vibration is excited in the flexible planar body 1 by the wind. Then, the flexible planar body 1 changes its form following the pressure distribution that changes every moment of the wind, generates a fluttering following the pulsation of the wind, and the pressure of the wind applied to the flexible planar body 1 Such vibrations that absorb energy are excited.

That is, the energy converter of the present inventionone ofIs arranged at a position where it is exposed to a flow of fluid such as wind, and at least a part of the peripheral edge can flutter almost freely by the flow.ClothA flexible plane body, an energy conversion section that converts vibration energy into electrical energy, and a vibration that is coupled to the flexible plane body and that is generated in the flexible plane body by the flow is transmitted to the energy conversion section.
In this manner, the piezoelectric bimorph element 3a of the lower end side piezoelectric energy conversion unit 31 is displaced in the same direction as the vibration direction by the vibration energy that has reached the lower end side piezoelectric energy conversion unit 31, and in response to this change. FIG. 7 is a graph showing experimental results in the fourth embodiment of the present invention. FIG. 5 shows changes (waveforms) in the output voltages of the upper rotary generator 103 and the second lower rotary generator 105. As the flexible planar body 101 flutters, the leeward reinforcing upper corner portion 1012 and the lower end side peripheral portion 1013 of the flexible planar body 101 swing in a direction perpendicular to the wind direction. In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention..
