摩擦电纳米发电机（Triboelectric nanogenerator，TENG）是一种新发明的技术，它有效地利用具有功能化表面的传统有机材料将机械能转化为电能，具有重量轻，成本效益高，易于扩展等优点。本文首次从EMIG和TENG的工作机理、控制方程和输出特性等方面对这两种技术进行了系统的分析和比较，旨在建立这两种技术在获取各种机械能方面的互补应用。探讨了两种外电路电源的等效变换和求并运算，为TENG可以看作大内阻电流源，而EMIG可以看作小内阻电压源提供了适当的依据。本文提出的理论比较和实验验证的基础上，使用TENG作为一种新的能源技术，可以并行或可能同等重要的EMIG的一般电力应用在大规模。它为化学家和材料科学家开辟了一个有机纳米发电机的领域，他们可以首次使用传统的有机材料将机械能高效地转化为电能。
Triboelectric nanogenerator (TENG) is a newly invented technology that is effective using conventional organic materials with functionalized surfaces for converting mechanical energy into electricity, which is light weight, cost-effective and easy scalable. Here, we present the first systematic analysis and comparison of EMIG and TENG from their working mechanisms, governing equations and output characteristics, aiming at establishing complementary applications of the two technologies for harvesting various mechanical energies. The equivalent transformation and conjunction operations of the two power sources for the external circuit are also explored, which provide appropriate evidences that the TENG can be considered as a current source with a large internal resistance, while the EMIG is equivalent to a voltage source with a small internal resistance. The theoretical comparison and experimental validations presented in this paper establish the basis of using the TENG as a new energy technology that could be parallel or possibly equivalently important as the EMIG for general power application at large-scale. It opens a field of organic nanogenerator for chemists and materials scientists who can be first time using conventional organic materials for converting mechanical energy into electricity at a high efficiency.
