Title:
TRIBOELECTRIC NANOGENERATOR AND WIND SPEED AND WIND DIRECTION SELF-DRIVING SENSING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/000542
Kind Code:
A1
Abstract:
Disclosed are a triboelectric nanogenerator (TENG) and a wind speed and wind direction self-driving sensing apparatus. The TENG comprises a wind chamber having a slit effect, a friction electron layer, and a hydroxyethyl cellulose film; the wind chamber is provided with an ingress end and an egress end; a layer of electrodes and a friction electron layer are respectively fixedly adhered to an upper side surface and a lower side surface of an inner wall of the wind chamber; the middle of the wind chamber near the ingress end is provided with a support strip that is horizontally arranged and that is perpendicular to the wind direction; and one end of the hydroxyethyl cellulose film is fixedly adhered to the support strip, and the other end freely extends towards the egress end. The sensing apparatus comprises a plurality of TENGs, which are fixed at intervals in the radial direction at a central angle of 45° on the circumference of a ring, and which are all connected to an electrometer digital acquisition board. The present invention has the features of high sensitivity, a large effect range, and simple preparation, and can maintain stable operation for a long time; in addition, sensing of low wind speed can be implemented by using a slit effect, which can be used for wind speed sensing and wind energy collection, so as to supply energy to agricultural sensors.
