摘要
摩擦纳米发电技术是一种基于电负性不同的材料,通过静电感应和摩擦起电的耦合作用实现材料间电荷转移,从而将环境能量转化为电能的能量俘获技术.因在物联网及其相关智慧产业以及新能源等领域的巨大应用潜力,摩擦纳米发电俘能技术自被提出后便受到极大地关注并成为国内外的研究热点.将非线性力学机制拓展至摩擦纳米发电俘能技术构造的非线性摩擦纳米发电机在低频环境激励下具有复杂的非线性动力学行为,可以产生大幅值动力学响应,进而高效地将低频环境能量转化为电能.文章首先简要介绍了摩擦纳米发电俘能原理与非线性摩擦纳米发电机的基本工作原理,然后从双稳态摩擦纳米发电俘能、多稳态摩擦纳米发电俘能和准零刚度摩擦纳米发电俘能等3个方面详细总结了非线性摩擦纳米发电俘能方法的研究工作.此外,从碰撞式摩擦纳米发电俘能、混合机制摩擦纳米发电俘能等两个方面详细阐述了非线性摩擦纳米发电俘能系统的性能提升策略.最后,通过总结非线性摩擦纳米发电俘能技术的研究进展,分析了目前研究中的不足,并对未来非线性摩擦纳米发电俘能技术的研究方向进行了展望.
Abstract
Triboelectric nanogenerator(TENG)technology is a kind of energy harvesting technology based on materials with different electronegativity,which realizes charge transfer between materials through the coupling effect of electrostatic induction and triboelectric,so as to convert environmental energy into electric energy.Due to its huge application potential in the fields of the Internet of Things and its related smart industries and new energy,the TENG technology has received great attention and become a research hotspot at home and abroad since it was proposed.The nonlinear mechanical mechanism is extended to the TENG,which has complex nonlinear dynamic behavior under the excitation of low frequency environment and can generate large dynamic response,and then efficiently convert the low frequency environmental energy into electric energy.In this paper,the principle of energy harvesting by TENG(e.g.,the sliding-mode TENG and the contact-separation mode TENG)and the basic working principle of nonlinear TENG are briefly introduced.Then,the research work of energy harvesting by nonlinear TENG is summarized in detail from three aspects:bistable TENG,multistable TENG and quasi-zero-stiffness TENG,etc.,that are employed to harvest low-frequency ambient energy.Moreover,the fundamental principle of these nonlinear TENGs and the typical researches are reviewed as well.Meanwhile,it can be clearly seen that the frequency band of the energy harvesting of the nonlinear TENG is narrow,and the electrical output of the nonlinear TENG should be further improved.To address these issues,the researchers have proposed a lot of methods to improve the electrical performance of the nonlinear TENG.The performance improvement strategy of the nonlinear TENG is described in detail from two aspects,such as impact-mode TENG and hybrid TENG.Finally,this paper summarizes the research progress of nonlinear TENG,analyzes the shortcomings of current research,and prospects the future research direction of nonlinear TENG technology.
