| 초록 | Electronic textile (E-textile) where various electronic elements are integrated on fabrics have received tremendous attention for advanced wearable and flexible devices which are considered as the next generation technologies. Especially, textile-based applications such as pressure sensors and strain sensors have been widely studied for detecting vital signals of patients, medical diagnostics, and human body motion detection by embedding them in clothes. For the realization of ultra-sensitive textile-based sensor applications, various types of sensing mechanisms such resistive, capacitive, piezoelectric, piezoresistive, and optical types have been introduced. In general, sensor applications should consist of conductive materials for electrical operation in aforementioned mechanisms. However, it is very challenging to demonstrate textile-based sensor applications with conventional conductive materials due to the low mechanical properties such as flexibility and stretchability. Furthermore, unfamiliar textures of the conventional conductive materials hindered its practical usage. Herein, we describe a novel method of fabricating ultra-sensitive sensor applications based on highly conductive and stretchable fibers. The fabrication of conductive and stretchable fiber is based on chemical reduction process of metal ions in elastomeric polymer. We use this concept to make ultra-sensitive textile-based capacitive pressure sensor and highly stretchable conductive fiber-based resistive strain sensor. The textile-based pressure sensors were successfully applied to control robots by detecting hand motion using the fabric pressure sensor-integrated gloves. We also successfully utilized the fiber-based strain sensor for detecting simple sign language. |
