Abstract: " With the development of technology, smart wearable devices are becoming increasingly popular in daily life. To achieve the intelligent functions of these devices, the number of integrated modules and the complexity of power supply systems have continually increased, posing higher demands on power transmission cables suitable for flexible smart wearable devices. In this context, textile power cables, as a power transmission solution featuring multi-wire arrangement, have demonstrated great potential for application in smart wearable devices. Textile power cables have many advantages compared to traditional power cables. Traditional power cables are usually rigid and lack sufficient flexibility and comfort, which may cause discomfort to users when worn. In contrast, textile power cables, through the use of flexible materials and innovative structural designs, provide better adaptability and wearing experience, particularly suitable for smart clothing that requires prolonged wear. Many scholars have designed and prepared various types of textile cables using different materials and structures, showing the application prospect of textile power cables in smart wearable devices. These studies show that by selecting appropriate materials and structures, the flexibility and wearability of textile power cables can be significantly improved. This study innovatively designed a power cable webbing suitable for multi-wire expansion and high elasticity requirements, proposed a novel design scheme for elastic conductive wrapping yarn based on a spiral structure, where metal wires were spirally wrapped around the surface of an elastic spandex core yarn to achieve both conductivity and elastic performance. A flattened webbing with a tubular three-layer structure was designed to maintain structural stability and high resilience under mechanical strain. Combined with shuttle loom forming technology, a double-warp rapier loom was utilized in conjunction with differential grouping warp tension adjustment technology to control the warp stretch ratio or let-off amount during weaving. Based on the parallel resistance theorem, the collaborative optimization mechanism between the number of conductors and material combinations was explored and the structural and power transmission performance of the power cable webbing were evaluated. The results show that this study has innovatively designed a power cable webbing suitable for multi-wire expansion and high elasticity requirements, which not only achieves a combination of conductivity and elastic performance but also ensures structural stability and high recoverability under mechanical strain. This study successfully prepared an elastic cable webbing with good power transmission performance, providing a novel and efficient solution for power transmission in flexible smart wearable devices. This design holds broad application prospects and will play an important role in smart clothing and other flexible electronic devices in the future."
