| 제목 | Mechanism Analysis of Buckled Shell Structure Formation on the Surface of Stretchable Ag Conductive Fiber |
| 초록 | Recently, a lot of researches on flexible and stretchable textile electronics have been proceed because they can be easily applied to wearable devices. In particular, textile electronics were developed in the form of sensor for various purpose, such as pressure sensors, strain sensors, and gas sensors. Recently, various bio-inspired approaches to change the structure of the surface of conductive fiber have been tried in order to enhance the performance of the fiber-type sensor, and as a result, the sensitivity of the fiber-type sensor has been greatly improved. However, the fiber-type sensors still have limitations such as low reliability and durability under the external force condition. In this study, we developed a method for forming buckled shell structures on the surface of stretchable conductive fibers. In addition, we analyzed and optimized the formation mechanism of buckled shell structure, thus, we fabricated the buckled shell structured conductive fiber with excellent mechanical and electrical performance. It maintained stable electrical resistance even under the external force condition, and based on this, the reliability of the fiber-type sensor has been improved. Furthermore, it is expected to increase the sensitivity of gas sensors and chemical sensors based on the greatly increased surface area per unit length. In future research, the buckled shell structured conductive fiber is expected to significantly contribute to improving the performance and stability of wearable devices by simultaneously perform as a stable interconnector and a reliable fiber-type sensor. |
