Abstract
This manuscript presents the development of a nanograting assisted Triboelectric Nanogenerator (TENG) for improved performance. The TENG leverages a cost-effective and straightforward fabrication method, utilizing nano-gratings on a Polydimethylsiloxane (PDMS) layer to enhance the triboelectric effect. The device characteristics are evaluated by considering tapping force, separation distance, and load resistance. The experimental electrical characterization shows that the output voltage increases significantly with higher applied forces, with a 2 N force generating voltage increases of over 584% compared to a 0.1 N force. Conversely, the output voltage decreases as the separation distance is reduced. The charge storage capability of the proposed device is demonstrated by integrating a TENG with a full-wave bridge rectifier. Furthermore, the fabricated TENG demonstrates remarkable sensitivity in detecting various body motions. When strategically placed on the biceps, the TENG effectively tracks muscle contraction and expansion with a voltage range of +0.5 V to -1 V, exhibiting a sensitivity of 1.5 V per cycle. Similarly, the TENG accurately detects bending movements in the knee and elbow joints. For knee bending, the voltage output ranges from +2.5 V to -1 V, resulting in a sensitivity of 3.5 V per cycle. Elbow flexion generates voltages between +4 V and -5 V, corresponding to a sensitivity of 9 V per cycle. This clear correlation between voltage and specific body movements makes the TENG a promising candidate for wearable health and motion monitoring systems.
本手稿介绍了一种纳米光栅辅助三电纳米发电机(TENG)的开发情况,以提高其性能。该 TENG 采用了一种成本效益高且简单的制造方法,利用聚二甲基硅氧烷(PDMS)层上的纳米晶格来增强三电效应。通过考虑敲击力、分离距离和负载电阻,对器件特性进行了评估。实验电气特性表明,输出电压随着施加的力越大而显著增加,与 0.1 N 的力相比,2 N 的力产生的电压增加了 584% 以上。相反,输出电压会随着分离距离的减小而降低。通过将 TENG 与全波桥式整流器集成,证明了所提器件的电荷存储能力。此外,所制造的 TENG 在检测各种身体运动时表现出了非凡的灵敏度。当战略性地将 TENG 放置在肱二头肌上时,它能在 +0.5 V 至 -1 V 的电压范围内有效跟踪肌肉的收缩和扩张,每个周期的灵敏度为 1.5 V。同样,TENG 还能准确检测膝关节和肘关节的弯曲运动。膝关节弯曲时,电压输出范围为 +2.5 V 至 -1 V,灵敏度为每周期 3.5 V。肘关节弯曲产生的电压在 +4 V 至 -5 V 之间,灵敏度为每周期 9 V。电压与特定身体运动之间的这种明显相关性使 TENG 成为可穿戴健康和运动监测系统的理想候选产品。
