The color-tuning capability of solid-state lighting (SSL) systems are highly demanded for smart lighting according to the environmental conditions, as well as wireless sensing of the environmental information. In the meanwhile, state-of-the-art triboelectric nanogenerator (TENG)-based sensing systems rely on bulky and expensive devices, which require cable connections and additional power consumptions. This work aims at solving these challenges, through developing a tribo-induced color tuner that can be integrated into the vastly distributed commercial SSL system. This tribo-induced color tuner includes a concentric color conversion plate consisting of (Sr,Ca)AlSiN3:Eu phosphor and TiO2, a tribo-induced liquid lens, and a rotary freestanding sliding TENG. The color oscillation between purple and pink is achieved upon the tribo-charging by the TENG, which reveals the input mechanical motion signals. The signal can be conveniently sent by everywhere-existed lamps and processed by everyone-owned smartphone cameras or closed-circuit televisions. Through this approach, the function of wireless sensing is achieved without the need of preamplification, with no additional power supply required, as demonstrated for wireless sensing of the rotation speed. The smart lighting for underwater photographing is also demonstrated by the color-tunable SSL system with the best imaging quality achieved.

面向智能照明和自供电无线传感的摩擦感应颜色调谐器
智能照明对固态照明（SSL）系统的颜色调节能力提出了很高的要求，该系统可以根据环境条件进行调色，并无线感测环境信息。与此同时，最先进的基于摩擦纳米发电机（TENG）的传感系统依赖于笨重且昂贵的设备，这需要电缆连接和额外的功耗。这项工作旨在通过开发一种摩擦引起的颜色调谐器来解决这些挑战，该颜色调谐器可以集成到广泛分布的商业 SSL 系统中。该摩擦引起的颜色调谐器包括由(Sr,Ca)AlSiN 3 :Eu磷光体和TiO 2组成的同心颜色转换板、摩擦引起的液体透镜和旋转独立式滑动TENG。TENG 摩擦充电时会实现紫色和粉色之间的颜色振荡，从而揭示输入的机械运动信号。该信号可以通过随处可见的灯方便地发送，并由每个人拥有的智能手机摄像头或闭路电视进行处理。通过这种方法，无需前置放大，无需额外电源即可实现无线传感功能，如转速无线传感所示。色彩可调的 SSL 系统也展示了水下摄影的智能照明，实现了最佳的成像质量。
