Nowadays, people can receive several types of information from portable and wearable devices. However, the limited working time period, rigid characteristic, and bulky size of the conventional power sources need to be improved for rocketing the compatibility with portable and wearable devices. In this paper, a flexible hybrid nanogenerator (FHNG) is presented by combining a solar cell, a transparent triboelectric nanogenerator (TENG), and a piezoelectric nanogenerator (PENG). The FHNG can sustainably collect energy from various energy sources. The FHNG can act as a self-powered weather monitoring device by harvesting and detecting raindrops, wind, and sunlight. Especially, the FHNG can simultaneously harvest both electro-static energy and impact energy of raindrops by the TENG and PENG parts, respectively. Owing to the hydrophobic surface of the outermost TENG part, the FHNG obtains a self-cleaning characteristic which can improve the output performance of the FHNG under sunlight and raindrops. Furthermore, the FHNG can be used as a wearable self-powered healthcare monitoring device by sensing the health information, such as human motion, arterial pulse rate, or respiration rate based on the electrical output when attached to a human body. This research contributes to broadening the coverage of self-powered nano-device in portable and wearable electronics.

用于自供电天气和医疗保健监测传感器的灵活混合纳米发电机

如今,人们可以从便携式和可穿戴设备接收多种类型的信息。然而,传统电源的工作时间有限、刚性特性和体积庞大,需要改进,以提高与便携式和可穿戴设备的兼容性。在本文中,通过结合太阳能电池、透明摩擦纳米发电机(TENG)和压电纳米发电机(PENG),提出了一种柔性混合纳米发电机(FHNG)。FHNG 可以可持续地从各种能源中收集能量。FHNG 可以通过收集和检测雨滴、风和阳光来充当自供电的天气监测设备。特别是,FHNG 可以分别通过 TENG 和 PENG 部件同时收集雨滴的静电能和冲击能。由于最外层 TENG 部分的疏水表面,FHNG 获得了自清洁特性,可以提高 FHNG 在阳光和雨滴下的输出性能。此外,FHNG 可用作可穿戴的自供电医疗保健监测设备,通过在连接到人体时基于电输出来感应健康信息,例如人体运动、动脉脉搏率或呼吸率。这项研究有助于扩大自供电纳米设备在便携式和可穿戴电子产品中的覆盖范围。当附着在人体上时,动脉脉搏率或基于电输出的呼吸率。这项研究有助于扩大自供电纳米设备在便携式和可穿戴电子产品中的覆盖范围。当附着在人体上时,动脉脉搏率或基于电输出的呼吸率。这项研究有助于扩大自供电纳米设备在便携式和可穿戴电子产品中的覆盖范围。
