Textiles hold great promise as a soft yet durable material for building comfortable robotic wearables and assistive devices at low cost. Nevertheless, the development of smart wearables composed entirely of textiles has been hindered by the lack of a viable sheet-based logic architecture that can be implemented using conventional fabric materials and textile manufacturing processes. Here, we develop a fully textile platform for embedding pneumatic digital logic in wearable devices. Our logic-enabled textiles support combinational and sequential logic functions, onboard memory storage, user interaction, and direct interfacing with pneumatic actuators. In addition, they are designed to be lightweight, easily integrable into regular clothing, made using scalable fabrication techniques, and durable enough to withstand everyday use. We demonstrate a textile computer capable of input-driven digital logic for controlling untethered wearable robots that assist users with functional limitations. Our logic platform will facilitate the emergence of future wearables powered by embedded fluidic logic that fully leverage the innate advantages of their textile construction.
纺织品作为一种柔软但耐用的材料，具有很大的应用潜力，可以低成本地制造舒适的机器人可穿戴设备和辅助设备。然而，完全由纺织品组成的智能可穿戴设备的发展受到了阻碍，因为缺乏一种可行的基于薄片的逻辑架构，可以使用传统的织物材料和纺织制造工艺来实现。在这里，我们开发了一种完全基于纺织品的平台，用于在可穿戴设备中嵌入气动数字逻辑。我们的逻辑功能纺织品支持组合和顺序逻辑功能、板载内存存储、用户交互以及与气动执行器的直接接口。此外，它们设计为重量轻、易于集成到常规服装中、采用可扩展的制造技术制造，并且足够耐用，可以承受日常使用。我们展示了一种能够进行输入驱动的数字逻辑控制的纺织品计算机，用于控制无需系绳的可穿戴机器人，以帮助功能受限的用户。我们的逻辑平台将促进未来的嵌入式流体逻辑驱动的可穿戴设备的出现，这些设备将充分利用其纺织品结构的固有优势。
