With the successive advent of piezoelectric nanogenerator (PENG) and triboelectric nanogenerator (TENG), the harvest of ambient mechanical energy has become more high-efficient, low-lost and simpler for self-powered systems. Introducing lightweight alternative power source to bionic micro aerial vehicle (BMAV) which is widely used for military surveillance or monitoring air pollution and so on, is the forefront of the research hotspots. However, there is still no design applying the two kinds of nanogenerator (NG) together in BMAV to collect the flapping mechanical energy more efficiently. In this paper, we demonstrate a hybrid flexible nanogenerator (HFNG) based on the combination of triboelectric and piezoelectric devices in BMAV. It not only can solve the problem of power supply, but also make the BMAV intelligent to monitor the changes of specific environmental factors. The newly designed HFNG can produce a maximum open-circuit voltage of 80 V, short-circuit current of 3.0 μA with the instantaneous output power density of 34.1 mW/m2 when the flapping frequency of BMAV (f) is 14 Hz. The rectified output of HFNG has been applied to charge the commercial capacitor, rechargeable battery and drive light-emitting diodes. It was also demonstrated that HFNG can be used for testing the lift force (L) of BMAV. Moreover, the output performances of HFNG have been proved to be sensitive to temperature, humidity, alcohol concentration and PM2.5 in the environment.

自供电混合柔性纳米发电机及其在仿生微型飞行器中的应用

随着压电纳米发电机(PENG)和摩擦电动纳米发电机(TENG)的相继问世,对于自供电系统,环境机械能的收集变得更加高效,低损耗且更加简单。向仿生微型飞行器(BMAV)引入轻巧的替代电源,该仿生微型飞行器(BMAV)被广泛用于军事监视或监视空气污染等,是研究热点。但是,仍然没有设计将两种纳米发电机(NG)一起应用在BMAV中,以更有效地收集拍动机械能。在本文中,我们演示了基于BMAV中摩擦电和压电装置组合的混合柔性纳米发电机(HFNG)。它不仅可以解决电源问题,同时也使BMAV能够智能地监视特定环境因素的变化。新设计的HFNG可以产生80 V的最大开路电压,3.0μA的短路电流以及34.1 mW / m的瞬时输出功率密度2当BMAV(的扑动频率˚F)为14赫兹。HFNG的整流输出已用于为商用电容器,可充电电池和驱动发光二极管充电。还证明了HFNG可用于测试BMAV的升力(L)。此外,事实证明,HFNG的输出性能对环境中的温度,湿度,酒精浓度和PM2.5敏感。
