使用电子纺织品向人体提供电子功能对于实现可穿戴电子产品的未来非常重要。印刷是大规模制造电子纺织品的有前途的方法，因为它使用简单且廉价的工艺实现任意图案。然而，由于纺织品的可变形和多孔结构，印刷在纺织品顶部的导电油墨容易破裂。通过控制油墨在织物结构中的渗透，开发了一种机械和电气坚固的布线。这是通过调整油墨的溶剂来完成的。丁基卡必醇乙酸酯的使用具有低蒸汽压和沸点，能够深入渗透到纺织品中。薄层电阻最初为0.06 Osq（-1），并且在拉伸至450%应变后电阻仅增加70倍。最后，展示了一种四通道肌电图（EMG）监测服装，以显示用于医疗保健和运动的大型电子纺织设备的潜力。
Delivery of electronic functionality to the human body using e-textiles is important for realizing the future of wearable electronics. Printing is a promising process for large scale manufacturing of e-textile since it enables arbitrary patterns using a simple and inexpensive process. However, conductive inks printed atop of textile are vulnerable to cracking because of the deformable and porous structure of textiles. The authors develop a mechanically and electrically robust wiring by controlling ink permeation in the structure of textile. This is done by adjusting the ink's solvent. The use of butyl carbitol acetate, with its low vapor pressure and boiling point, enables deep permeation into the textile. The sheet resistance is initially 0.06 O sq(-1), and the resistance increasing only 70 times after stretching to 450% strain. Finally, a four-channel electromyogram (EMG) monitoring garment is demonstrated to show the potential of a large-scale e-textile device for health care and sports.
