A hybridized blue energy harvester based on triboelectric-electromagnetic hybridized generator is developed to extract the abundant energy from water waves. Within the pendulum design of the blue energy harvester, an interdigital electrodes based triboelectric nanogenerator (I-TENG), a switches based triboelectric nanogenerator (S-TENG) and an electromagnetic generator (EMG) are complementarily integrated, to more effectively scavenge the water wave energy after packaged in a waterproof enclosed box. The outputs of both TENGs are enhanced by an optimized flexible circular ring supporting a rolling magnet due to soft contact and induced larger contact area. With a novel designed hybridized circuit, output power can reach to 95.4 mW at load of 100Ω. After the management circuit, a lithium battery of 200 mAh can be charged from 3.07 V to 3.35 V by this blue energy harvester with six hours of water wave impaction. Besides using the hybridized blue energy harvester to power a digital temperature sensor directly and continuously, an all-weather IoT platform is also established with the blue energy harvester, a solar cell panel and a Bluetooth sensor module. The ambient information of humidity and temperature can be detected and sent to user-end by the Bluetooth sensor module under various conditions with or without daylight and water waves.

开发了一种基于摩擦电磁混合发电机的蓝色混合能量采集器，以从水波中提取大量能量。在蓝色能量收集器的摆式设计中，基于叉指电极的摩擦纳米发电机（I-TENG），基于开关的摩擦纳米发电机（S-TENG）和电磁发电机（EMG）相互补充集成，以更有效地清除水波包装在防水的密闭盒中后的能量。通过优化的柔性圆环来增强两个TENG的输出，该圆环由于软接触和感应更大的接触面积而支撑滚动磁体。采用新颖设计的混合电路，在100Ω负载下输出功率可以达到95.4 mW。在管理电路之后，可以将3.0伏特的200 mAh锂电池充电至3。这个蓝色能量采集器在35 V电压下产生了六个小时的水波冲击。除了使用混合的蓝色能量采集器为数字温度传感器直接连续供电外，还建立了一个全天候的物联网平台，其中包括蓝色能量采集器，太阳能电池板和蓝牙传感器模块。可以在各种条件下（无论有无日光和水波），通过蓝牙传感器模块检测湿度和温度的环境信息，并将其发送到用户端。
