According to the present invention, a wind power harvesting power generator comprises: a first power generating unit formed of a conductive material and capable of flowing by wind force; a second power generating unit generating triboelectrification by contact and separation action with the first power generating unit; and a collecting unit connected to the first and second power generating units and collecting electricity induced by the triboelectrification. A surface of at least one of the first and second power generating units is formed of a non-planar surface having a high surface roughness by depositing a friction material to cause a frictional force upon contact with the other surface. An effective area for triboelectrification by such configuration is increased, thereby contributing to the improvement of a power generation rate. 개시된 본 발명에 의한 풍력 하베스팅 발전장치는, 전도성 재질로 형성되며 풍력에 의해 유동 가능한 제1발전유닛, 제1발전유닛과의 접촉 및 분리 작용으로 마찰 대전을 발생시키는 제2발전유닛 및 제1 및 제2발전유닛과 연결되어 마찰 대전에 의해 유도된 전기를 수집하는 수집유닛을 포함하며, 제1 및 제2발전유닛 중 적어도 어느 하나의 표면은 다른 하나의 표면과의 접촉시 마찰력을 야기하도록 마찰물질이 증착되어 표면 거칠기(surface roughness)가 높은 비평탄면으로 형성된다. 이러한 구성에 의한 마찰 대전을 위한 유효면적이 증대되어, 발전율 향상에 기여할 수 있게 된다.
