This study focused on the designs for the pulley and electric cables for Hello, the artwork displayed at the Great Hall at the Incheon International AirportTerminal 2. This study presented designs for the pulley and cables, and the parts were applied and tested to analyze their durability and problems. Improvements were made for the final production of the work and three samples were produced respectively for the designs of the pulley and the cables. As are sult, this study found that for the pulley, the most efficient design was to fix the cables at its center. In the case of cables, it was most efficient touse flat cables with a wire in the core. These designs were applied to the artwork Hello, which is currently installed at the Great Hall at the Incheon International Airport Terminal 2. Future research will be conducted to make further improvements to the cable sand the pulley.

In this study, we investigated the necessary mechanical properties of conductive multifilament yarns for fabricating the electrodes of biosignal measurement pressure and stretch textile sensors using embroidery. When electrodes and circuits for smart wearable products are produced through the embroidery process using conductive multifilament yarns, unnecessary material loss is minimized, and complex electrode shapes or circuit designs can be produced without additional processes using a computer embroidering machine. However, because ordinary missionary threads cannot overcome the stress in the embroidery process and yarn cutting occurs, herein, we analyzed the S-S curve, thickness, and twist structure, which are three types of silver-coated multifilament yarns, and measured the stress in the thread of the embroidery simultaneously. Thus, the required mechanical properties of the yarns in the embroidery process were analyzed. In the actual sample production, cutting occurred in silver-coated multifilament rather than silver-coated polyamide/polyester, which showed the lowest S-S curve. In the embroidery process, the twist was unwound through repetitive vertical movement. Further, we fabricated a piezoresistive pressure/tension sensor to measure gauge factor, which is an index for measuring biological signals. We confirmed that the sensor can be applied to the fabrication of embroidery electrodes, which is an important process in the mass production of smart wearable products.
