PURPOSE: A device and a method for generating electric power, and a sensor including the same are provided to reduce labor force and costs required for supplying electric power, and to improve convenience by charging a battery by itself. CONSTITUTION: A sensor including a device for generating electric power comprises an electric energy generating unit(110), a charging unit(120), and a transmitting-receiving unit. The electric energy generating unit generates electric energy using pressure or wind generated by external moving materials. The charging unit charges power using the electric energy. The transmitting-receiving unit is driven using the charged power, and transmits and receives a RF signal. |
