منسوجات با دوام بالا با استفاده از MWCNT برای سنجش حرکت High durability conductive textile using MWCNT for motion sensing

1. Introduction The demand for wearable devices has increased exponentially in recent years. So far, most of the commercialized wearable devices have been limited to accessories such as watches, bands, and glasses. To improve existing products, more flexible and biocompatible wearable parts have been studied [1-4]. In addition, there have been many research studies on integrating clothing and smart devices [5-7], which makes it necessary to maximize the flexibility of smart device parts. Stretchable conductive textiles are also an important element in smart clothing. Conductive textiles can be used as sensors for monitoring human motion through changes in the electrical resistance to varying strain rates. Smart clothing for sensing motion would be useful in various fields such as sports, games, and medical care. In particular, smart clothing is expected to be useful in the medical field due to increasing life expectancy. As the aging population increases worldwide, smart clothing will be increasingly adopted as routine elements of preventative medicine, monitoring and treatment of chronic diseases [8-10]. Low-cost home healthcare monitoring systems, which include smart clothing based on textile sensors, flexible circuits, and wireless communication [11-12], have attracted the attention of researchers and medics [13]. Smart clothing for health monitoring will help to improve the quality of life and decrease medical expenses for disease management by providing long-term sensing of bio-signals with minimal intrusion in the daily activities of patients. Smart clothing that can sense bio-signals of electrocardiograms, electromyograms, respiration, body movement, and skin temperature is already under development [14].
