The wearable electronic devices have been widely applied to types of wearable devices such as smartwatch, clothing, and medical device. Wearable devices use highly flexible sensors. The conductive substrate used for the flexible sensor have been manufactured by applying materials such as CNT, graphene, and conductive polymers to using spray, padding, and electrospinning process. But, the conductive substrate prepared by the spray process is easily fragile due to the lack of durability. We developed high-performance conductive nonwoven was fabricated by depositing MWCNTs on cellulose nonwoven composited with carbon fibers using a spray process to assign conductivity and then electrospinning thermoplastic polyurethane on MWCNTs to improve surface durability. Also, the prototype sensor was fabricated using the developed conductive nonwoven, and sensor function was demonstrated. This study expects that flexible conductive nonwoven can be effectively used in wearable devices sensors. |
