With the increasing deterioration of the natural environment, exploiting clean and renewable energy has become the top priority of scientific research today. One of the most prospective routes is to harvest water wave energy using triboelectric nanogenerator (TENG). In this work, a spherical TENG based on spring-assisted multilayered structure was fabricated to collect multidirectional water wave energy, and a power management module (PMM) was integrated to manage the output energy. The output performance of the TENG device was found to be controlled by the water wave frequency, amplitude, and orientation angle between the triggering direction and middle plane. Furthermore, with the PMM, the spherical TENG could output a steady direct current (DC) voltage on a resistance, and the charging speed to a supercapacitor was improved by 100 times. The power-managed performance of the whole TENG was also influenced by the circuit connection configurations among multilayered TENGs. A digital thermometer and a water level detection/alarm system were successfully driven by the power-managed TENG as the demonstrated applications. This work not only provides a type of spherical TENG capable of harvesting multidirectional water wave energy, but also effectively manages the output energy for practical applications toward blue energy. Our study demonstrates a typical example of how to build a self-charging power pack that can effectively use random energy in a regulated manner.

集成功率管理模块的球形摩擦电纳米发电机,用于收集多向水波能量

随着自然环境的日益恶化,开发清洁和可再生能源已成为当今科学研究的重中之重。最有前景的途径之一是使用摩擦电纳米发电机(TENG)收集水波能量。在这项工作中,制造了一个基于弹簧辅助多层结构的球形TENG以收集多向水波能量,并集成了一个电源管理模块(PMM)来管理输出能量。发现TENG装置的输出性能受触发方向与中间平面之间的水波频率,幅度和方向角的控制。此外,使用PMM,球形TENG可以在电阻上输出稳定的直流(DC)电压,并且超级电容器的充电速度提高了100倍。整个TENG的功率管理性能还受到多层TENG之间的电路连接配置的影响。作为演示应用,由功率管理的TENG成功驱动了数字温度计和水位检测/报警系统。这项工作不仅提供了一种能够收集多方向水波能量的球形TENG,而且还可以有效地管理输出能量,以用于实际应用中的蓝色能量。我们的研究表明了一个典型的示例,该示例说明了如何构建一种可自我调节的电源组,该电源组可以有效地以受控方式使用随机能量。作为演示应用,由功率管理的TENG成功驱动了数字温度计和水位检测/报警系统。这项工作不仅提供了一种能够收集多方向水波能量的球形TENG,而且还可以有效地管理输出能量,以用于实际应用中的蓝色能量。我们的研究表明了一个典型的示例,该示例说明了如何构建可以以调节方式有效利用随机能量的自充电式电源组。作为演示应用,由功率管理的TENG成功驱动了数字温度计和水位检测/警报系统。这项工作不仅提供了一种能够收集多方向水波能量的球形TENG,而且还可以有效地管理输出能量,以用于实际应用中的蓝色能量。我们的研究表明了一个典型的示例,该示例说明了如何构建可以以调节方式有效利用随机能量的自充电式电源组。
