초록
피부 활성점(경혈) 측정 방법은 편리성, 저비용 및 비 침습으로 측정하기 때문에 많은 생체정보를 얻기 위한 기술이다. 본연구에서는 피부 아래에 활성점을 측정할 수 있는 장점이 있는 3전극 측정방법을 사용되었다. 임피던스측정방법은 측정실험결과와 관련성이 있는 등가전기회로를 통해서 증명되었다. 활성점의 특성주파수는 주변 피부보다 15-30Hz 높고, 리액턴스는35-77kΩ 더 작게 측정되었다. 이 기술은 비침습 측정 시스템을 이용해서 활성점과 주변피부의 리액턴스와 특성주파수를 정확하고 객관적으로 분석되었다.
Abstract
The method of measuring skin active points is a technique for obtaining a lot of biometric information because it ismeasured with convenience, low cost and non-invasive methods. In this paper, we used in a three electrode measuremethod that has the advantage of measuring the impedance of the APs under the skin. The impedance measuring methodis well illustrated by a simple model of an equivalent electrical circuit that correlates well with experimental results. Thecharacteristic frequencies of APs are about 15-30HZ higher than that of surrounding skin and the values of measuredreactance are about 35-77KΩ smaller. This technology analyzed accurately and objectively the reactance and characteristicfrequency of APs and the surrounding skin using a non-invasive measuring system.
