摘　　要：热声发动机作为一种新型的外燃式热机,具有可靠性高、使用寿命长、环境友好等优点,在热声发电、热驱动制冷等领域具有重要应用前景。本文结合热声技术和摩擦纳米发电技术的特点,首次提出了"热声驱动摩擦纳米发电机"这一热-声-电换能新流程。理论计算了驻波热声发动机和接触分离式摩擦纳米发电机采用末端耦合结构时的换能特性,并开展了系统实验研究。实验中,热声驱动摩擦纳米发电机获得了最高10 V的开路电压输出;在外接电阻为400 MΩ时,最高输出功率为0.008μW,验证了"热声驱动摩擦纳米发电机"这一概念的可行性。As a new type of external combustion heat engine with advantages of high reliability,long service life and environmental friendliness,thermoacoustic heat engine(TAHE) has shown potential in applications such as electricity generation and heat driven refrigeration.In this paper,we propose a thermoacoustically driven triboelectric nanogenerator(TA-TENG) by combining the respective characteristics of thermoacoustic technology and triboelectric nanogenerator technology.The energy conversion performance is theoretically calculated and experimentally investigated on the basis of the structure that a contact-separation mode type triboelectric nanogenerator coupling at the resonator end of a standing-wave TAHE.In the experiment,the TA-TENG produces a maximum output voltage of 10 V and a corresponding output power of 0.008 μW with a load of 400 MΩ,demonstrating the viability of TA-TENG.
