AI 中文摘要
可拉伸混合电子学将刚性固态电子器件与可拉伸材料及结构相集成，以实现高可拉伸性与稳定的电子性能。然而，现有多数系统仅将可拉伸性视为机械属性，未利用器件形变编码自身机械状态，该问题源于将传统刚性电路架构适配到可拉伸基底，导致其与应变测量所需传感器的兼容性下降。本研究提出一种面向可拉伸混合器件的通信集成形变感知架构以解决该问题：在该方案中，刚性节点间传输的标准通用异步收发传输器（UART）数字信号，会被可拉伸液态金属互连线路因应变产生的电阻变化进行幅度调制；通过读取幅度变化与数字模式，系统可在无需额外可拉伸传感元件的情况下，实现同步数字通信与自身形变感知。该架构在多节点系统中得到验证，并应用于可穿戴传感与自身形变映射设备。本研究将刚性电路与软元件的集成从硬件层面拓展至系统层面，为可拉伸电子系统提供了一种新颖的设计范式，该范式将器件自身形变固有地用作功能信息。
英文摘要
Stretchable hybrid electronics integrate rigid solid-state electronics with stretchable materials and structures to achieve both high deformability and stable electronic performance. However, most existing systems treat stretchability only as a mechanical attribute without exploiting device deformation to encode its own mechanical state. This problem arises from adapting conventional rigid circuit architectures to stretchable substrates, affording a loss in compatibility with the sensors required for strain measurement. This study addresses this issue by proposing a communication-integrated deformation sensing architecture for stretchable hybrid devices. In the proposed approach, standard universal asynchronous receiver-transmitter digital signals transmitted between rigid nodes are amplitude-modulated by strain-induced resistance changes in stretchable liquid metal interconnects. By reading both amplitude changes and digital patterns, the system enables simultaneous digital communication and self-deformation sensing without requiring additional stretchable sensing elements. The architecture is demonstrated in a multi-node system and applied to wearable sensing and self-deformation mapping devices. By extending the integration of rigid circuits and soft elements from the hardware level to the system level, this study provides a novel design paradigm for stretchable electronic systems that inherently utilize their own deformation as functional information.
