Self-powered sensor networks are an emerging technology with great potential applications in Internet of Things (IoTs). However, simultaneously harvesting various coexist energy from environment has always been a challenge to develop self-powered sensor networks. In this work, a tumbler-shaped hybrid triboelectric nanogenerator (TH-TENG) is elaborately designed to simultaneously harvest wind and water wave energy on land or ocean. The TH-TENG is composed of an external single-electrode liquid TENG and an internal rolling-ball TENG. The balance-reverting tumbler structure contributes to harvest energy from arbitrary directions and extra swings. Amphibious self-powered environmental monitoring including the wind speed, wave height and wave frequency can be detected by the TH-TENG directly. Meanwhile, the TH-TENGs can also be integrated in parallel to power a commercial environmental monitor. The detection of small vibration is achieved by connecting the TH-TENG with a single chip microcomputer. The TH-TENG demonstrates an effective and novel strategy to harvest coexist energy simultaneously in the amphibious environment and develop wireless sensor networks in the IoTs.

不倒翁形混合摩擦纳米发电机,用于两栖自供电环境监测

自供电传感器网络是一种新兴技术,在物联网(IoT)中具有巨大的潜在应用。然而,从环境中同时收集各种共存能量一直是发展自供电传感器网络的挑战。在这项工作中,精心设计了一个不倒翁形的混合摩擦电纳米发电机(TH-TENG),以同时在陆地或海洋上收集风能和水波能。TH-TENG由外部单电极液体TENG和内部滚动球TENG组成。平衡平衡的翻转杯结构有助于从任意方向和额外的摆动中收集能量。TH-TENG可以直接检测两栖自供电环境监测,包括风速,波高和波频率。与此同时,TH-TENG也可以并行集成,以为商用环境监测器供电。通过将TH-TENG与单片机连接,可以检测到较小的振动。TH-TENG展示了一种有效且新颖的策略,可以在两栖环境中同时收集能量并开发物联网中的无线传感器网络。
