Wearable photonics offer a promising platform to complement the thriving complex wearable electronics system by providing high‐speed data transmission channels and robust optical sensing paths. Regarding the realization of photonic computation and tunable (de)multiplexing functions based on system‐level integration of abundant photonic modulators, it is challenging to reduce the overwhelming power consumption in traditional current‐based silicon photonic modulators. This issue is addressed by integrating voltage‐based aluminum nitride (AlN) modulator and textile triboelectric nanogenerator (T‐TENG) on a wearable platform to form a nano‐energy‐nano‐system (NENS). The T‐TENG transduces the mechanical stimulations into electrical signals based on the coupling of triboelectrification and electrostatic induction. The self‐generated high‐voltage from the T‐TENG is applied to the AlN modulator and boosts its modulation efficiency regardless of AlN's moderate Pockels effect. Complementarily, the AlN modulator's capacitive nature enables the open‐circuit operation mode of T‐TENG, providing the integrated NENS with continuous force sensing capability which is notably uninfluenced by operation speeds. Furthermore, a physical model is proposed to describe the coupled AlN modulator/T‐TENG system. With the enhanced photonic modulation and the open‐circuit operation mode enabled by synergies between the AlN modulator and the T‐TENG, optical Morse code transmission and continuous human motion monitoring are demonstrated for practical wearable applications.

具有自持光子调制和连续力传感功能的可穿戴摩擦电/氮化铝纳米能量纳米系统。

可穿戴光子学提供了一个有前途的平台，通过提供高速数据传输通道和强大的光学传感路径来补充蓬勃发展的复杂可穿戴电子系统。对于基于丰富光子调制器的系统级集成来实现光子计算和可调谐（解）复用功能，降低传统基于电流的硅光子调制器中巨大的功耗具有挑战性。这个问题的解决方法是在可穿戴平台上集成基于电压的氮化铝（AlN）调制器和纺织摩擦纳米发电机（T-TENG），形成纳米能量纳米系统（NENS）。T-TENG 基于摩擦起电和静电感应的耦合将机械刺激转换为电信号。尽管 AlN 具有中等的普克尔斯效应，但 T-TENG 自生的高压会施加到 AlN 调制器上，从而提高其调制效率。作为补充，AlN 调制器的电容特性支持 T-TENG 的开路运行模式，为集成 NENS 提供连续力传感能力，且不受运行速度的影响。此外，还提出了一个物理模型来描述耦合的 AlN 调制器/T-TENG 系统。通过 AlN 调制器和 T-TENG 之间的协同作用实现增强型光子调制和开路操作模式，光学莫尔斯电码传输和连续人体运动监测在实际可穿戴应用中得到了验证。
