摘要
人体呼吸是人体的一项重要生理功能,也是评估整体健康的关键指标,尤其是在睡眠不足的情况下。然而,开发一个用于检测睡眠姿势、心跳和呼吸的实时系统既具有挑战性,又至关重要。这种系统应易于制造、佩戴舒适、灵敏度高。在这项研究中,我们利用电纺丝技术制造了一种嵌入聚偏二氟乙烯(PVDF)纳米复合材料(NC)的柔性电纺丝钴铁氧体(CoFe2O4,CF)。此外,我们还研究了不同 CF 含量(0、1、3 和 5 wt%)对 PVDF 中结晶 β 相的影响。以 PVDF-CF (P-CF) NC 作为三电负极层,以热塑性聚氨酯(TPU)无纺布作为三电正极层,制作了三电纳米发电机(TENG)装置。在本研究中使用的四种样品组合中,P-CF-3(PVDF 中含有 3 wt% 的 CF)/TPU TENG 的三电开路电压(Voc)明显较高,达到 5.8 V,与 P-CF-0/TPU TENG(1.7 V)相比高出近三倍。这项工作展示了一种通过改变纳米填料浓度来提高柔性 TENG 器件输出功效的有效方法。此外,还对制造的 TENG 器件进行了有效测试,用于实时医疗保健监测(HCM)和多导睡眠图(PSG)相关研究。这项研究旨在为实时识别睡眠障碍和呼吸监测提供一种新颖实用的方法。
Cobalt ferrite-embedded polyvinylidene fluoride electrospun nanocomposites as flexible triboelectric sensors for healthcare and polysomnographic monitoring applications
Human respiration is a vital physiological function of the body and a key metric for assessing overall health, particularly in conditions related to sleep deprivation. However, developing a real-time system for detecting sleeping position, heartbeat, and respiration is challenging yet crucial. Such a system should be easy to fabricate, comfortable to wear, and highly sensitive. In this study, we fabricated a flexible electrospun cobalt ferrite (CoFe2O4, CF) embedded polyvinylidene fluoride (PVDF) nanocomposite (NC) using an electrospinning technique. Additionally, we investigated the influence of varying CF content (0, 1, 3, and 5 wt%) on the crystalline β-phase in PVDF. The triboelectric nanogenerator (TENG) device was fabricated using PVDF-CF (P-CF) NC as the tribo-negative layer and non-woven fabric of thermoplastic polyurethane (TPU) as the tribo-positive layer. Among the four sample combinations used in this study, P-CF-3 (3 wt% CF in PVDF)/TPU TENG exhibited a significantly higher triboelectric open circuit voltage (Voc) of 5.8 V, nearly three times higher as compared to P-CF-0/TPU TENG (1.7 V). This work demonstrates an efficient method for enhancing the output efficacy of flexible TENG devices by varying the nanofiller concentration. Moreover, the fabricated TENG device was efficiently tested for real-time healthcare monitoring (HCM) and polysomnographic (PSG) related studies. This study aspires to provide a novel and pragmatic way of identifying real-time sleeping disorders and respiratory monitoring.
