Ever since a new energy harvesting technology, known as a triboelectric nanogenerator (TENG), was reported in 2012, the rapid development of device fabrication techniques and mechanical system designs have considerably made the instantaneous output power increase up to several tens of mW/cm². With this innovative technology, a lot of researchers experimentally demonstrated that various portable/wearable devices could be operated without any external power. This article provides a comprehensive review of polyvinylidene fluoride (PVDF)-based polymers as effective dielectrics in TENGs for further increase of the output power to speed up commercialization of the TENGs, as well as the fundamental issues regarding the materials. In the end, we will also review PVDF-based sensors based on the triboelectric and piezoelectric effects of the PVDF polymers.
自2012年一种名为摩擦纳米发电机（TENG）的新能源收集技术被报道以来，器件制造技术和机械系统设计的快速发展已使瞬时输出功率大幅提高至数十毫瓦每平方厘米。借助这项创新技术，许多研究人员通过实验证明，各种便携式/可穿戴设备无需任何外部电源即可运行。本文全面综述了聚偏二氟乙烯（PVDF）基聚合物作为TENG中有效的电介质，以进一步提高输出功率，加速TENG的商业化，以及与这些材料相关的基本问题。最后，我们还将综述基于PVDF聚合物的摩擦电和压电效应的PVDF基传感器。
