The flexible film 215 connects the two annular bodies 201a and 201b, and the force applied to the film 215 by the relative movement of the two annular bodies 201a and 201b accompanying the movement of the user in the piezoelectric element. Converted to electricity.

As described above, according to the present embodiment, electric power can be continuously supplied to the false nail 1 from the power transmitting device 2. Further, in the fake nail 1, the electric power supplied from the power transmitting device 2 is continuously charged to the battery 13, and the electric power is charged on the flexible display 11 by the charged electric power as shown in Figs. 8a, a, b, and c. The display of the displayed content, the slide display of a plurality of still pictures, and the display of the display content change.

The embodiments of the present invention have been described above.

As described above, according to the present embodiment, power generation in the power transmitting device 2 having a large space larger than the false nail 1 can generate more power than in the case where the power is generated in the fake nail 1. In addition, the power transmission by the magnetic field resonance method of the power transmission device 2 or the wireless power transmission of the ultrasonic method is performed so as to have directivity in the direction of the false nail 1 or wireless power transmission by power through the human body. On the other hand, electric power can be supplied from the power transmitting device 2 to the artificial nail 1 more efficiently and stably.

Therefore, according to the present embodiment, since the electric power can be continuously used in the dummy nail 1, the display of the display content change such as the animation display or the slide show in the fake nail 1 can be more continuously performed.

In the above embodiment, the power transmitting device 2 includes the power generating device 21. However, the power transmitting device 2 may be provided with a primary battery such as a button battery or a secondary battery that has been charged, instead of the power generating device 21.

Further, in the above embodiment, in addition to the configuration in which the power transmitting device 2 and the dummy nail 1 communicate with each other, the power transmitting device 2 can rewrite the animation of the memory 121 of the fake nail 1 and the data of the still picture.

Further, in the above embodiment, the flexible display 11 is preferably an electronic paper that can hold the display content even when no power is supplied. By using the electronic paper, even when the power can not be supplied from the power transmitting device 2 to the dummy nail 1, the display of the image in the fake nail 1 can be maintained.
