Power generating ear tag having adjustable angle for animals

Abstract

A power generating ear tag having an adjustable angle for animals, said ear tag comprising a main housing (1) and a fixing piece (2). The fixing piece (2) is connected to the main housing (1) by means of an angle adjustment structure (3). The angle adjustment structure (3) comprises a rotating seat (31) arranged on the main housing (1), a rotating cavity (32) is provided in the rotating seat (31), and the rotating cavity (32) has a plurality of slots (33) distributed at intervals in a circumferential direction. The angle adjustment structure further comprises a rotating head (34) arranged on the fixing piece (2) and extending into the rotating cavity (32), and the rotating head (34) is provided with a snap tab (35) that can rotatingly switch between the slots (33). The fixing piece (2) and the main housing (1) are connected by means of the angle adjustment structure (3). When applied to a specific animal, the angle is adjusted to test the performance at different angles, so as to optimize the contact conditions of a triboelectric nanogenerator unit (4). Thus, the triboelectric nanogenerator unit (4) is always maintained at the optimal angle during use, such that the generation of triboelectric charges is maximized. This dynamic adjustment mechanism significantly improves energy harvesting efficiency.
