Abstract
Natural materials are widely used in the preparation of Triboelectric nanogenerators (TENGs) because of their degradability, low cost and ease of preparation. Chitosan is one of the important ones. However, the lower dielectric constant of chitosan films affects their output performance. In this study, TiN particles were used to increase the dielectric constant of the films and the effect of different concentrations of TiN on the output performance was investigated. It was proved that at 8 wt %. concentration, the open-circuit voltage, short-circuit current were 67 V, 4.2 μA, and the power was 103.9 μW. In the actual test, it successfully powered the calculator and lit up eight blue LEDs. Finally, the TENG was successfully used to monitor human movement, and this study provides a viable path for TENGs based on degradable materials.
天然材料因其可降解性、低成本和易于制备而被广泛用于制备三电纳米发电机（TENGs）。壳聚糖就是其中重要的一种。然而，壳聚糖薄膜较低的介电常数会影响其输出性能。本研究使用 TiN 颗粒来提高薄膜的介电常数，并研究了不同浓度的 TiN 对输出性能的影响。结果表明，在 8 wt % 的浓度下，开路电压和短路电流分别为 67 V 和 4.2 μA，功率为 103.9 μW。在实际测试中，它成功地为计算器供电，并点亮了八个蓝色 LED 灯。最后，该 TENG 成功地用于监测人体运动，这项研究为基于可降解材料的 TENG 提供了一条可行的途径。
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications.
