Optical wireless communications (OWC), featuring a wide optical bandwidth and robust resistance to radio-frequency interference (RFI), can benefit the development of the Internet of Things (IoT). Making IoT devices ubiquitous calls for decentralized and on-demand power sources for wireless communications. However, existing visible-light-based self-powered OWC systems are complex on the receiver side, they are easily affected by ambient light, and they can disturb dark environments. In this paper, we realized self-powered infrared (IR) wireless communications via integrating a triboelectric nanogenerator (TENG) and an IR transmitter. With customized mechanical modulation protocols, both the frequency and amplitude features of the IR signal, enabled by different mechanical motion or mechanical structures of TENG devices, can be leveraged for conveying information. The concept of this TENG-enabled wireless infrared communications framework and the results from this study may pave the way for a new generation of self-powered communications in a sustainable manner.

用于红外无线通信的摩擦电纳米发电机启用的机械调制

光无线通信（OWC）具有宽光带宽和抗射频干扰（RFI）能力，有利于物联网（IoT）的发展。使物联网设备无处不在，需要分散和按需的无线通信电源。然而，现有的基于可见光的自供电OWC系统在接收端较为复杂，容易受到环境光的影响，并且会干扰黑暗环境。在本文中，我们通过以下方式实现了自供电红外（IR）无线通信集成了摩擦纳米发电机（TENG）和红外发射器。通过定制的机械调制协议，可以利用 TENG 设备的不同机械运动或机械结构实现的 IR 信号的频率和幅度特征来传递信息。这种支持 TENG 的无线红外通信框架的概念和这项研究的结果可能为新一代自供电通信以可持续的方式铺平道路。
