본 논문에서는 인간의 가장 기본적이며 기초적인 운동인 걸음걸이로부터 검출할 수 있는 걸음 수 및 보행분석을 위해 전도성 섬유를 이용한 전기용량성 압력 센서를 깔창형태로 개발하였다. 개발된 깔창 형태의 센서는 보행시의 압력을 측정하여 보행신호를 검출하고, 검출된 신호를 이용하여 걸음 수 및 자세에 따른 압력 분포를 관찰하였다. 개발된 센서의 성능 검증을 위하여 국제규격의 표준분동을 사용하여 0 kg에서 100 kg 까지 10 kg씩 증가하여 무게에 따른 압력변화를 관찰하였으며, 그 결과 압력에 따라 비선형적인 특성을 가지고 캐패시턴스 값이 증가함을 보였다. 자세에 따른 압력변화 실험과 보행 횟수 검출비교를 위한 실험에서는 건강한 성인남성 다섯 명을 대상으로 4가지의 서로 다른 자세로 있을 때의 압력 변화를 관찰하였고, 보행 횟수 검출을 위해서는 시속 1 km/h와 4 km/h의 두 가지 걸음속도에서 3분 동안 걷게 하여 보행신호를 검출하였다. 상용 만보계 및 관찰자의 수계로 도출된 보수를 비교하였다. 기존의 상용 만보계는 저속(1 km/h)으로 걸었을 때 보수가 잘 측정되지 않은 반면 개발된 센서는 저속에서도 관찰자 수계대비 정확한 보수를 도출 할 수 있었다(상용 만보계 대비 평균 98.06 %의 인식률). 또한 자세에 따라 압력 값을 토대로 사용자의 자세를 모니터링 할 수 있음을 보였다. 본 연구는 향후 스마트폰과 무선 연동하는 스마트 보행관리 시스템을 개발하기 위한 기초연구이다.

In order to develop "textile electrode - sensing clothing" which is a sort of smart clothing to measure electric activities of heart, we propose possible ways to develop textile electrode and design of sensing clothing, ultimately aiming to develop "ECG sensing clothing for lifestyle monitoring". Conventional sensors for measuring typical electric activities of heart keep certain distance between measuring electrodes to measure signals for electric activities of heart, but these sensors often cause inappropriate factors (e.g. motional artifacts, inconvenience of use, etc) for monitoring natural cardiac activities in our daily life. In addition, most of textile electrodes have made it difficult to collect data due to high impedance and unstable contact between skin and electrodes. To overcome these questions, we minimized distance between electrodes and skin to maximize convenience of use. And in order to complement contact between skin electrodes, we modified textile electrode's form and developed ways to design clothing. As a result, we could find out clinical significance by investigating possible associations of clinical electrocardiogram (ECG) with variation of distance between electrodes, and could also demonstrate clinically significant associations between textile electrode developed herein and clothing.

PCM has the ability to change their state, these materials absorb energy during the heating process as a body contact and release energy during a reverse cooling process as phase change take place. Using the thermal energy storage of PCM which has a melting point 15 to $35^{circ}C$ is one of the most effective ideas for utilization in textile finish. In this study, microencapsulated PCM(MCPCM) were synthesized by sol-gel method using the octadecane(or nonadecane) as PCM and the silica as microcapsule materials. To develop smart temperature adaptable textile, coating process was applied to textile substrate using a composition included MCPCM.

With the help of the cooperative efforts made in the interdisciplinary studies among the different fields of computers, textiles and computer in the modem society based on knowledge-information, Smart Clothing, which is the combination of wearable Technology and clothing has been drawn. This study is to inspect the design of Smart school uniform, which if based on Wearable Technology, to meet the need for the PDG(Post Digital Generation) who want to require rapid and the convenient information. This study is aimed to quest for the direction of study in Wearable Technology through theoretical studies made in the field the Computer information communications Engineering, seminars in the field of Smart Textile and documentary study. In addition to them, this study is to search for the value for the school uniform in the PDG who are a group of potential consumers for the Smart Clothing, the environment in digitalized life and the need for the Wearable Technology. Based on this research, the concept of design reflecting the need for the characteristic and functions in the PDG was drawn and Design Prototype of Smart Jacket on the base of Wearable Technology was presented.

The purpose of this research was to develop a smart wear equipped with wearable technologies for women in the age of 50's and 60's and confirm its acceptability. For this, we constructed a casual jacket that has the integration of heating and lighting function, and evaluated the user's satisfaction. The size of the heating device attached at the back of the jacket was 300 mm in width and 120 mm in length and the size of the one attached at the front abdomen was 180 mm in width and 120 mm in length. The power supplier was the unification of the battery and controller which have been waterproofed. The lighting device connected with LED was 26mm in width, 20 mm in length and 1.5 mm in thickness. It has been designed in a waterproofed rectangular shape and was attachable to the jacket. The satisfaction survey of a smart jacket has been conducted with three standards, which were convenience, appearance and practicality. Free physical movement among the standard of convenience had very high scores with the average of 4.7 on a five point-scale. The acceptability of the jacket was 4.6, which proved that it didn't have unique feelings compared to ordinary ones. The evaluation score of the appearance of the jacket was 4.5. Especially inside finishing of the jacket received the highest scores from all ages. According to the evaluation of practicality, there has been no change in the appearance of the jacket and the function of heating device after laundry.

This study is basic material for development of a smart girdle. Through the intentionally sampling of 313 consumers from teenagers to the forties who have experienced wearing girdles, lifestyles on consumer's age, attitude to health, favor of warm functional girdle, and possibility to acceptance were surveyed and analyzed by questionnaire. The result of the study are summarized as followed. 1. Analysis about lifestyle with warmth and attitude to health showed that subjects in their thirties and forties have higher than teenagers and the twenties in frequency of distribution. This means people are tend to have more attention to warmth and health as they grow older. 2. In result about analysis of characteristic of wearing girdle, subjects were prefer girdle made of cotton which have superior permeability and hygroscopic property. The reason that wearing girdle is to complement of weak points of body somatotype in the thirties and forties and feel the stability during menstrual period in the twenties and teenagers. The time zone of putting on girdle is mainly winter while one is out wearing one-piece or skirt. 3. When surveyed about the preference to functional warmth girdle and possibility to acceptance, the results were that the subjects in their thirties were first, forty something was second, followed by subjects in their twenties, teenagers. It was shown that over 60% subjects were highly distributed. With regard to necessity of functional warmth girdle, every age groups were shown over 3.6 at average. This result was inferred that subjects had positive possibility to acceptance about functional warmth smart girdle.

Recently, smart wearable products, including electromyography (EMG) measurement devices and clothing, have been developed to monitor users' exercise levels, muscle activation, and muscle balance more effectively during fitness activities. However, technical and socioeconomic barriers, such as flexibility and durability, still pose challenges in terms of comfort, ease of wear, and wearability of smart clothing, which includes devices and circuits. To address these issues, this study developed a wearable EMG device integrated with clothing to collect valid EMG signals from desired muscles while maintaining comfort, functionality, and ease of wear. After deriving a combined structure that could stably position the wearable device within the clothing, a prototype was manufactured and evaluated for fit, compression, comfort, and exercise comfort test by ten participants (height = 176.2 cm, weight = 76.4 kg, chest circumference = 101.2 cm). The study found that the prototype had smaller circumferences around the chest, waist, and abdomen compared to commercial products, resulting in lower ratings for wearing comfort and ease of wear. However, the prototype received high ratings for fitting, pressure, and the exercise comfort test. Valid signals were obtained when the EMG device was combined to the prototype for the rectus femoris muscle, indicating stable positioning of the device during exercise.
