Hybrid Electromagnetic‐Triboelectric Nanogenerator Based on BaTiO ₃ ‐CNT‐PDMS Composite for Wind Energy Harvesting

ABSTRACT Real‐time monitoring of poultry house environments is critical for optimizing farming efficiency and ensuring animal welfare. Current power supply systems face limitations such as high costs and complex installation in remote areas. This study proposes an embedded rotating triboelectric‐electromagnetic hybrid nanogenerator (ER‐TEHG) for wind energy harvesting, which can be used to power environmental monitoring systems in poultry farms. Our design integrates a triboelectric nanogenerator (TENG) and an electromagnetic generator (EMG) into a rotating structure. The TENG component uses barium titanate‐carbon nanotube‐polydimethylsiloxane (BaTiO ₃ ‐CNT‐PDMS) composite films and carbon cloth electrodes, with optimized dielectric properties to enhance charge density and surface charge transfer efficiency. The EMG component employs a magnetic flux slicing mechanism to maximize induced current generation. At a rotational speed of 240 rpm, the system outputs 1.4 mW (TENG), 60 mW (EMG), and 0.18 W (ER‐TEHG). This integrated system successfully powers temperature and humidity sensors, ammonia detectors, and ventilation fans through capacitor energy storage, demonstrating a fully self‐sufficient monitoring solution. This research not only addresses the urgent need for sustainable power sources in agricultural monitoring but also advances the practical application of hybrid energy harvesting technology in precision livestock farming.
