A triboelectric nanogenerator (TENG) is a promising energy harvester that exploits the combination of contact electrification between two different material surfaces and electrical induction. In this study, a handheld‐TENG (HH‐TENG) is developed to harvest biomechanical energy effectively, especially energy generated from finger motions, which is one of the most common body movements involving lots of energy. To enhance the electrical output performance of the device while minimizing the inconvenience caused by carrying it, a rationally designed lightweight power transmission unit is adopted. As a result, an extremely high number of output cycles with high specific peak power (greater than 10 µW g–1) can be achieved in a single operation of the HH‐TENG. Although the proposed HH‐TENG weighs less than 70 g, the developed HH‐TENG can be connected with commercially available electric circuits such as an AC‐DC converter to generate not only reliable and continuous DC voltage to power portable electronics, but also further boosted open‐circuit voltage greater than 2.5 kV, which is sufficient to generate microplasma in a room environment. Adoption of a lightweight power transmission unit with the TENG can be considered as an effective strategy to significantly enhance the specific power, which advances the TENG toward practical implementation.

开发具有轻型动力传输单元的高性能手持式摩擦电纳米发电机

摩擦电纳米发电机(TENG)是一种很有前途的能量收集器,它利用了两种不同材料表面之间的接触带电和电感应的组合。在这项研究中,开发了一种手持式TENG(HH-TENG),可以有效地采集生物机械能,特别是手指运动产生的能量,这是涉及大量能量的最常见的人体运动之一。为了提高设备的电输出性能,同时最大程度地减少由于携带而带来的不便,采用了合理设计的轻型动力传输单元。结果,具有很高的特定峰值功率(大于10 µW g –1)的输出周期数量非常多)可以通过HH-TENG的单个操作来实现。尽管拟议的HH-TENG重量不到70克,但已开发的HH-TENG可以与市售电路连接,例如AC-DC转换器,不仅可以产生可靠且连续的DC电压,为便携式电子设备供电,而且可以进一步提高其功率。开路电压大于2.5 kV,足以在室内环境中产生微等离子体。使用带有TENG的轻型动力传输单元可以被视为有效提高单位功率的有效策略,从而将TENG推向了实际实施。
