Abstract
(EN) A system for measuring bioimpedance, a bioimpedance measurement method, and a computer-readable recording medium for executing same in embodiments may comprise an electric current supply device for supplying an electric current to a human body, and a readout IC (ROIC) which in response to the supply of electric current, extracts an AC signal by attenuating a DC signal in a voltage generated from the human body, and amplifies and outputs the AC signal. The embodiments may implement an efficient system capable of improving energy efficiency while being able to simultaneously use two types of signals, AC impedance and DC impedance signals.
(FR) Système de mesure de bio-impédance, procédé de mesure de bio-impédance, et un support d’enregistrement lisible par ordinateur pour l’exécuter dans des modes de réalisation pouvant comprendre un dispositif d’alimentation de courant électrique pour alimenter un courant électrique à un corps humain, et un CI de lecture (ROIC) qui en réponse à l’alimentation de courant électrique, extrait un signal CA par l'atténuation d’un signal CC dans une tension générée à partir du corps humain, et amplifie et émet le signal CA. Les modes de réalisation peuvent mettre en œuvre un système efficace capable d’améliorer l’efficacité énergétique tout en étant capable d’utiliser simultanément deux types de signaux, les signaux d’impédance CA et d’impédance CC.
(KO) 실시예의 바이오 임피던스 계측용 시스템, 바이오 임피던스 계측 방법 및 이를 수행하기 위한 컴퓨터 판독 가능한 기록매체는 인체에 전류를 공급하는 전류 공급 장치와, 전류의 공급에 응답하여 인체로부터 나온 전압 중 DC 신호를 상쇄시켜 AC 신호를 추출하고, 상기 AC 신호를 증폭시켜 출력하는 ROIC(Readout IC)를 포함할 수 있다. 실시예는 전력 효율을 향상시킬 수 있으며, 동시에 DC 임피던스 신호와 AC 임피던스 두 종류의 신호를 모두 이용할 수 있는 효율적인 시스템을 구현한 효과가 있다.
