摘要
最近,机械能收集器已成为自供电传感器和小型电子设备的理想选择。本研究开发了用于能量收集的铝铁氧体 (AlFeO3)/PVDF 混合包晶电纺纳米纤维基三相增强压电纳米发电机 (TPENG)。制作完成的 TPENG 实现了 52.3 V 的平均电压输出和 1.23 µA 的平均电流输出。此外,经计算,在 80 MΩ 外部电阻负载下,TPENG 的功率密度为 0.085 W.m-2。三维打印设备包含尼龙织物(三极正极)作为转子,连接到打印鳍片上,而六个用 Kapton 胶带(三极负极)包裹的 (AlFeO3)/PVDF 混合包晶电纺纳米纤维压电纳米发电机(PENG)作为定子。该装置的三个印刷鳍片通过一个基于线的滑轮移动,可产生 200 V 的开路电压和 4.5 µA 的短路电流。带有 TPENGs 的 3D 打印设备可用于为小型电子设备(如 LED 和手表)和运动装置供电,让患者通过拉动连接的绳索来发电,从而估算损伤程度。将能量收集融入康复治疗可激励患者移动受损的身体部位,从而提高 TPENG 在医疗保健领域的应用,使其成为患者康复治疗的实用而有吸引力的工具。
Flexible Tribo-Enhanced Piezoelectric Nanogenerator Based on Aluminium Ferrite Electrospun Hybrid Nanofibers for Energy Harvesting and Patient Rehabilitation Application
Mechanical energy harvesters have recently emerged as promising options for self-powering sensors and small electronic devices. In this work, aluminum ferrite (AlFeO3)/PVDF hybrid perovskite electrospun nanofiber-based tribo-enhanced piezoelectric nanogenerators (TPENGs) are developed for energy harvesting. The as-fabricated TPENG achieves an average voltage output of 52.3 V and an average current output of 1.23 µA. Additionally, the power density of the TPENG is calculated to be 0.085 W.m−2 at an 80 MΩ external resistance load. A 3D-printed device is fabricated, containing nylon fabric (tribo-positive) as a rotor attached to printed fins, while six (AlFeO3)/PVDF hybrid perovskite electrospun nanofiber piezoelectric nanogenerators (PENGs) wrapped with Kapton tape (tribo-negative) serve as the stator. The three printed fins of the device are moved by a string-based pulley, generating an open circuit voltage of 200 V and a short circuit current of 4.5 µA. The as-fabricated 3D-printed device with TPENGs is used to power small electronics (e.g., LEDs and watch) and an exercise setup, allowing patients to generate power by pulling the attached string, thereby estimating the level of impairment. Integrating energy harvesting into rehabilitation motivates patients to move impaired body parts, enhancing TPENG's application in healthcare as a practical and engaging tool for patient rehabilitation.
