The present disclosure provides a triboelectric nanogenerator structure composed of an upper electrode layer, a lower triboelectric layer, a lower electrode layer and an electric connecting member. The upper electrode layer is composed of a hybrid gel. The lower triboelectric layer corresponding to the upper electrode layer has a first surface and a second surface. The first surface faces toward the upper electrode layer. The second electrode layer is disposed at the second surface. The electric connecting member connects the upper electrode layer to the lower electrode layer. Therefore, the triboelectric nanogenerator is humidity-independent and has a stable output characteristic. |
