PURPOSE: A woolen fabric type energy harvesting device using a piezoelectric fiber is provided to generate electrical energy in a first electrode and a second electrode, thereby efficiently harvesting the energy. CONSTITUTION: A first electrode (230) is arranged on one side of a piezoelectric fiber (210). A second electrode (240) is arranged on the other side of the piezoelectric fiber. A support layer is arranged on a part of the surface of the piezoelectric fiber. The piezoelectric fiber is differently transformed by external force. An insulating layer is arranged on a part of the surface of the first electrode or the second electrode. |
