Abstract

In this study, antennas for passive UHF RFID tags were created from a carbon-based stretchable conductor on a stretchable elastic band by brush-painting. The antennamicrochip interconnections were fabricated by two different ways: 1) by using already commonly reported gluing with conductive silver epoxy and 2) by sewing the IC with conductive yarn. In addition to wireless evaluation of the fabricated RFID tags before and after stretching, we evaluated the effects of the interconnection type on tag performance and reliability. The achieved read ranges of around 1.5 meters are suitable for versatile textile-integrated RFID applications. Stretching causes permanent decrease to the tag read range but they remain functional even after 100 stretching cycles. In addition, the tags with the embroidered interconnections were found to be more reliable towards harsh stretching, compared to the tags with glued ICs. These initial results are very encouraging, considering the current trend towards more ecofriendly and cost-effective materials in electronics.

可穿戴无线平台的纺织集成可拉伸结构

在这项研究中，无源超高频RFID标签的天线是由可拉伸弹性带上的碳基可拉伸导体通过刷涂制成的。天线微芯片的互连是通过两种不同的方式制造的:1)使用已经普遍报道的导电银环氧树脂粘合，2)用导电纱缝制集成电路。除了在拉伸前后对制造的RFID标签进行无线评估外，我们还评估了互连类型对标签性能和可靠性的影响。实现的读取范围约为1.5米，适用于多功能纺织品集成RFID应用。拉伸导致标签读取范围的永久减少，但即使在100次拉伸循环后，它们仍保持功能。此外，与粘接ic的标签相比，带有刺绣互连的标签在严酷拉伸时更可靠。考虑到目前电子产品中更环保、成本效益更高的材料的趋势，这些初步结果非常令人鼓舞。
