With the increasing pursuit of intelligent systems, the integration of human components into functional systems provides a promising route to the ultimate human-compatible intelligent systems. In this work, we explored the integration of the human hand as the powerless and multiplexed infrared (IR) light source in different functional systems. With the spontaneous IR radiation, the human hand provides a different option as an IR light source. Compared to engineered IR light sources, the human hand brings sustainability with no need of external power and also additional level of controllability to the functional systems. Besides the whole hand, each finger of the hand can also independently provide IR radiation, and the IR radiation from each finger can be selectively diffracted by specific gratings, which helps the hand serve as a multiplexed IR light source. Considering these advantages, we show that the human hand can be integrated into various engineered functional systems. The integration of hand in an encryption/decryption system enables both unclonable and multilevel information encryption/decryption. We also demonstrate the use of the hand in complex signal generation systems and its potential application in sign language recognition, which shows a simplified recognition process with a high level of accuracy and robustness. The use of the human hand as the IR light source provides an alternative sustainable solution that will not only reduce the power used but also help move forward the effort in the integration of human components into functional systems to increase the level of intelligence and achieve ultimate control of these systems.
随着对智能系统的不断追求，将人类组件集成到功能系统中为最终实现与人兼容的智能系统提供了一条有前途的途径。在这项工作中，我们探索了将人手作为无能力和多路复用的红外（IR）光源集成到不同功能系统中的方法。人手通过自发的红外辐射提供了一种不同于传统工程 IR 光源的选择。与工程化的 IR 光源相比，人手具有可持续性，无需外部电源，并且为功能系统提供了额外的可控性。除了整个手之外，人手的每个手指也可以独立提供 IR 辐射，并且每个手指的 IR 辐射可以通过特定的光栅选择性地衍射，这有助于人手成为多路复用的 IR 光源。考虑到这些优势，我们展示了如何将人手集成到各种工程功能系统中。在手加密/解密系统中的集成可以实现不可克隆和多级信息加密/解密。我们还演示了在复杂信号生成系统中使用人手，以及在手语识别中的潜在应用，这表明了一种简化的识别过程，具有高精度和鲁棒性。将人手用作 IR 光源提供了一种替代的可持续解决方案，不仅可以减少使用的功率，还有助于推动将人类组件集成到功能系统中的努力，以提高智能水平并实现对这些系统的最终控制。
