최근 생체 신호 측정을 위한 기능성 의류는 동작 잡음에 의한 노이즈를 최대한 줄여 정확한 생체 신호를 측정 가능케 하는 것의 중요성에 대한 논의가 이루어지고 있다. 이에 본 연구는 영향 요인별 고려 사항을 반영하여 3-리드(lead)방식의 은사 자수의 직물 전극을 개발하고, ‘일자형 절개 타입’, ‘십자형절개 타입’, ‘엑스형 절개 타입’, ‘곡선 엑스형 절개 타입’의 총 네 가지 타입의 생체신호 센싱 스마트 의류의 시안을 설계하고 제작하였다. 디자인 시안은 민소매형태의 남성용 티셔츠로 신축성 있는 소재를 사용하여 인체 굴곡을 따라 의복과 전극이 밀착될 수 있도록 하였으며, 트랜스미터를 이용하여 메인 컴퓨터로 데이터가 무선 전송되게 하였다. 각 재모듈화형 의류 타입별 인체 동작에 의한 영향과 정지 및 동작 상태에서의 심전도 센싱 성능을 평가하기 위해 동작에 따른 전극의 변위를 측정하고, 심전도 측정 평가를 실시하여 SNR을 분석하였다. 본 실험 결과를 반영하여 의류 디자인 시안의 수

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 ca

A soft wearable robotic garment was developed to support lumbar muscle function and postural alignment by using cell-structured fabric pneumatic artificial muscles (cfPAMs). The actuator was constructed from two types of lightweight thermoplastic polyurethane-coated nylon fabrics and was designed with a flexible structure to enhance the contraction and force output. The performance of three actuator configurations (3-cell, 6-cell, and 8-cell) was evaluated in terms of contraction ratio, force ge

Considering increasing demand for improved waist protectors for the elderly, in this study we sought to design a waist protector that reflects the body characteristics, preferences, and satisfactions of the elderly. A survey conducted to investigate elderly satisfaction with existing waist protectors, as well as their preferences in product function, design, and characteristics, found that consumers are not satisfied with current waist protector offerings and would prefer protectors that allow g

This study is a longitudinal analysis of works featured in the exhibition catalogs of the Korean Society of Costume (KOSCO) from 2016 to 2025, with focus directed toward changes in exhibition themes, compositions, and modes of expression. Exhibition themes have evolved and expanded from an early concentration on international exchange to more profound contemporary discourses involving issues such as sustainability, reglobalization, the modern reinterpretation of tradition, and the convergence of

Assistive soft wearable robots are widely spreading with the promise of helping individuals with reduced mobility in everyday life. For these robots to provide effective assistance in real-life environments, they require real-time accurate recognition of user activities and detection of gait events. However, wearable robots often have limited sensory equipment because of lightweight and wearability constraints. We previously developed a clothing-type soft wearable robot that supports walking by
