Topic
인간 피부에 삽입형 전극 설계를 위한 생체 임피던스 특성을 확인하고 최적의 전극 디자인을 도출하는 것을 목표로 하였다.
📖
Background
생체 전극의 접촉 저항은 전기적 임피던스 측정의 정확성을 제한하는 주요 요소로, 본 연구는 인체의 다양한 피부 층에서 생리적 변화를 탐지하기 위해 생체 임피던스 값을 바탕으로 최적 설계를 추구한다.
🔬
Method
전극의 길이(50 mm, 70 mm), 재질(금), 모양(직사각형, 둥글기둥, 육각기둥) 및 깊이(22.325 mm)에 따라 유한요소법(FEM)을 사용하여 다양한 전극 디자인을 비교하고 분석하였다.
🏆
Result
생체 임피던스 실험을 통해 전극의 모양과 인가 전압에 따라 피부의 피하조직에서 가장 큰 임피던스 차이를 확인하였으며, 흥미로운 결과는 육각기둥 모양의 전극이 임피던스 측정에서 가장 큰 값을 나타내었다.

Electrode contact resistance is a crucial factor in physiological measurements and can be an accuracy limiting factor to perform electrical impedance measurements. The electrical bio-impedance values can be calculated by the conductivity and permittivity of underlying tissue using implant electrode in human skin. In this study we focus on detecting physiological changes in the human skin layers such as the sebum layer, stratum corneum layer, epidermis layer, dermis layer, subcutaneous fat and muscle. The aim of this paper is to obtain optimal design for implantable electrode at subcutaneous fat layer through the simulation by finite element methods(FEM). This is achieved by evaluating FEM simulations geometrically for different electrodes in length(50 mm, 70 mm), in shape(rectangle, round square, sexangle column), in material(gold) and in depth(22.325 mm) based on the information coming from the subcutaneous fat layer. In bio-impedance measurement experiments, according to electrode shapes and applied voltage, we have ascertained that there was the highest difference of bio-impedance in subcutaneous fat layer. The methodology of simulation can be extended to account for different electrode designs as well as more physical phenomena that are relevant to electrical impedance measurements of skin and their interpretation.
