In this paper, we demonstrate a newly designed hybridized triboelectric nanogenerator (TENG) fabric incorporating multiple working modes, which can effectively harvest ambient mechanical energy for conversion into electric power by working in a hybridization of a contact-separation mode, a sliding mode and a freestanding triboelectric layer mode. The power generation of each mode of the TENG fabric was systematically investigated and compared along different directions, under different frequencies and at different locations. Owing to the advanced structural design, the as-fabricated TENG fabric could be switched between multiple working modes according to its real working situation. High output voltage and current of about 140 V and 0.6 μA, respectively, were obtained from a larger size of TENG fabric, which could be used to light up 120 LEDs in series. Compared to the previously reported TENGs, such a hybridized TENG fabric based on hybridized modes has much better adaptability for harvesting energy (such as human walking, running, and other human motion) in different directions. This work presents the promising potential of hybridized TENG fabric for power generation and self-powered wearable devices.
在本文中，我们展示了一种新设计的具有多种工作模式的杂交摩擦纳米发电机（TENG）织物，它可以通过在接触-分离模式、滑动模式和独立摩擦电层模式的混合状态下工作，有效地收集环境机械能并将其转化为电能。我们系统地研究并比较了TENG织物在不同方向、不同频率和不同位置时各模式的发电情况。由于先进的结构设计，所制备的TENG织物能够根据实际工作情况在多种工作模式之间切换。从较大尺寸的TENG织物中分别获得了约140 V和0.6 μA的高输出电压和电流，该织物可用于串联点亮120个发光二极管。与先前报道的TENG相比，这种基于混合模式的杂交TENG织物在收集不同方向的能量（如人类行走、跑步和其他人体运动）方面具有更好的适应性。这项工作展示了杂交TENG织物在发电和自供电可穿戴设备方面的广阔潜力。
