저비용 스트레처블 탄소 흑연 복합제 전극 개발

Stretchable electrodes are being manufactured through various materials and methods, and many mechanical properties analysis is being studied. It is studied based on various metals such as silver, copper, gold, and nano-wire or CNT, graphene, and fluren, and most of them are used in applications that require high conductivity and stretch properties, but there is a disadvantage of high price. In this study, a stretchable electrode with high elasticity and repetitive properties was developed with low-cost materials and processes. The paste was developed by mixing cheap conductive carbon and graphite, and the developed paste was printed on the TPU substrate through metal mask printing process and cured for two hours at 120℃. The developed electrodes were characterized by tensile and tensile repetition tests, and the results of the temporary fixation on the knee to check the applicability of the application in the future showed a constant change of resistance
