본 논문은 전도성섬유 압력센서로 보행신호를 획득하고 걷기, 서기, 앉기, 계단오르기, 계단내려오기 등 총 5가지 행동을 인식하는 시스템을 개발하는 것이 목적이다. 시스템은 Capacitive pressure 센서, CDC(Capacitive to Digital Converter), 마이크로프로세서, 블루투스 모듈, 스마트 폰으로 구성되고 획득한 데이터 패턴을 분류한 결과 평균 99.5%의 높은 인식률을 보였다. 각 발당 한 개의 채널만을 이용해 행동패턴을 인지함으로써 적은 수의 채널로도 행동인지의 가능함을 확인할 수 있었다.

The combination of developed medical devices and the convergence of IT fusion technologies, health variables became to can be measured without discomfort in everyday life regardless of wherever and whenever. because various types of u-Health medical devices have been developed. Also, by considering the users, biological signals can be measured without difference with wearing general clothing, that conductive fabric is being used as smart clothing. However, considering that there is a growing prevalence of the devices and a great interest in the development of u-Health devices, it is urgent to establish performance evaluation. Accordingly, writing guidelines by force to raise checking before marketed or collecting checks after at the market for standard test methods for evaluating the performance. In this paper, it was studied that the possibility of using conductive fabric as electrodes for Wearable u-Health Devices through the material test of the ffabric.

Manufacture of nancomposites has simple process for developing nanocomposites due to the increasing applications using nanofillers. This work studied nanofiller coated glass fiber for reinforcing material with good wetting and conductivity and the morphology of nanofiller coated glass fiber was analyzed by FE-SEM. The durability of reinforced glass fiber was investigated with different shapes of nanofillers using sonication rinsing method. Fatigue test was performed to evaluate the adhesion of reinforcing interface and stability of nanofiller coating layer for single fiber reinforced composites. Apparent modulus and conductivity of nanofiller coating layer were evaluated to realize multifunctional of nanocomposites. Fiber type of nanofiller was better than plate type due to better cohesion between fiber and nanofillers. At last, the stability of fiber type nanofiller of coating layer has better durability and conductivity than plate type case.

Electrically conductive carbon fiber/high density polyethylene (CF/HDPE) composite films were fabricated by new method, so called electron-ion technology (EIT) and the effects of CF epoxy sizing on the volumetric resistivity. tensile strength and interphase properties of the films were investigated. While epoxy sizing increased conductivity of composite films resulting from enhanced tunneling effect it reduced interphase adhesion between CF and HDPE because polar epoxy sizing and nonpolar HDPE are incompatible. Consequently epoxy sized CF(CF(S)) caused significant reduction in the volumetric resisitivity and tensile strength of composite films when compared with unsized CF(CF(U)). Epoxy sizing reduced nucleating efficiency of CF(S), therefore CF(S)/HDPE composite films showed nonuniform transcrystalline layer when compared with CF(U)/HDPE composite films.
