本简报提出了一种用于无电池分布式可穿戴模块的导电纺织品互连方案。采用由绝缘织物层分隔的两层导电纺织品作为传输线，可同时传输直流电力和基于脉冲的数据信号，无需点对点布线。为最小化每个模块的电路开销，通用异步收发器（UART）脉冲通过交流耦合电容直接耦合到纺织品上，无需载波调制。纺织品波形被建模为二阶电路的瞬态响应，针对基于比较器的波形恢复和高比特率传输的设计条件得到了解析推导。所提出的设计框架可确定给定数据速率、纺织品电容和电阻的组合是否可行，还能提供对应的去耦电感器设计范围。这些结果为基于纺织品的电力与数据同时传输建立了基础方法。
英文摘要
This brief presents a circuit-level conductive-textile interconnection technique for batteryless distributed wearable modules. Two conductive textile layers separated by an insulating fabric layer are used as a garment-wide shared bus that simultaneously conveys DC power and pulse-based data signals without point-to-point wiring. To minimize the circuit overhead of each module, universal asynchronous receiver/transmitter (UART) pulses are directly coupled onto the textile through AC-coupling capacitors without carrier modulation. The textile is modeled as a lumped resistance--capacitance network. The textile waveform is then modeled as the transient response of a second-order circuit. From this model, design conditions for comparator-based waveform recovery and high-bitrate transmission are analytically derived. The resulting design framework determines whether a given combination of data rate, textile capacitance, and resistance is feasible, and also provides the corresponding design range of the decoupling inductors. The required textile parameters are characterized, and robustness to parameter drift is analyzed. These results establish a basic methodology for textile-based simultaneous power and data transfer.
