The frequent occurrence of natural disasters is a major threat to the property and casualties of human beings in recent decades. Disaster prone points can be very closely monitored by augmenting the distribution of wireless sensor networks. However, replacing the battery of electronics regularly remains a significant challenge especially in a remote area. In this study, we report a wind-driven hybridized energy harvester which is designed for rotating energy harvesting and can be integrated with WSN technology to develop a self-powered natural disaster monitoring system. In this harvester, the rotator is directly driven by external rotational motion thus can easily hybridize the TENG with eighteen EMGs. Consequently, the fully packaged WH-EH device combining with the water-proof flexible solar cell can be completely isolated from the harsh wilderness environment. The output feature of TENG of high voltage but low current that perfectly compensate for the differing performance of EMG to achieve an excellent output power of the hybrid device with a broad frequency range. Moreover, the WH-EH is capable of lighting hundreds of LEDs and powering small electronics. The quick-acting charging ability of a capacitor by the WH-EH was conducted effectively in experimental tests. Finally, three self-powered sensor systems enabled by a single WH-EH were discussed and demonstrated, including a temperature sensor for forest fire detection, a vibration sensor for earthquake monitoring and a wireless transceiver for alarm information spreading. Obviously, the invention of the hybridized nanogenerator will be of great importance to promote the development of self-powered wireless sensor networks and provide a sustainable power-supply solution to long-term natural disaster monitoring stations in residential or remote areas.

近几十年来，自然灾害的频繁发生是对人类财产和人员伤亡的重大威胁。通过增加无线传感器网络的分布，可以非常紧密地监视易受灾点。但是，定期更换电子设备电池仍然是一个巨大的挑战，尤其是在偏远地区。在这项研究中，我们报告了一种风能混合式能量收集器，该收集器设计用于旋转能量收集，并且可以与WSN技术集成以开发自供电的自然灾害监测系统。在这种收割机中，转子由外部旋转运动直接驱动，因此可以轻松地将TENG与18个EMG进行杂交。所以，完全包装的WH-EH装置与防水柔性太阳能电池相结合，可以与恶劣的野外环境完全隔离。高电压但低电流的TENG输出特性可以完美补偿肌电图的不同性能，从而在宽频率范围内实现混合动力设备的出色输出功率。此外，WH-EH能够点亮数百个LED并为小型电子设备供电。WH-EH对电容器的快速充电能力在实验测试中得到了有效的体现。最后，讨论并演示了由单个WH-EH启用的三个自供电传感器系统，包括用于森林火灾检测的温度传感器，用于地震监测的振动传感器和用于警报信息传播的无线收发器。明显地，
