초록

With the rapid growth of the Internet of things in the recent years, smart textile technologies have correspondingly attracted significant research attention in the industry. One important elementary technology being considered for smart textiles is a touch sensor input device to enable direct communication between users and other electronic devices. This study investigated the effect of the structural difference in conducting fibers on the sensing property of capacitive textile touch sensors. Conducting fibers made of stainless steel spun yarns and filaments used for electrodes presented different changes in electrical resistance with the application of tensile and compressive forces. It is believed that the different structures between spun yarns and filaments induced difference in the electric contact among their constituent fibers with the application of an external force. Moreover, the random deformation of staple fibers resulted in the unstable change of capacitance and large hysteresis, while a stable performance and low hysteresis was observed for textile sensors with filaments.
