Abstract
A triboelectric nanogenerator with slit effect (SE-TENG) and a self-driven wind speed and wind direction sensing device. The TENG includes a wind cavity with slit effect, a triboelectric layer, a hydroxyethyl cellulose (HEC) film, and indium tin oxide (ITO) electrodes. The wind cavity is provided with an inlet end and an outlet end. A layer of the electrode and a triboelectric layer are fixedly adhered to the upper surface and the lower surface of an inner wall of the wind cavity. The wind cavity is provided with a horizontally arranged support bar perpendicular to a wind direction in a middle close to the inlet end. The HEC film includes one end fixedly adhered to the support bar, and the other end extending freely toward the outlet end. The sensing device includes a plurality of SE-TENGs which are fixed on a circumference of a ring. The sensing device can be used in an agricultural environment.
