More Information
Summary:An electrodermal activity measurement device with built-in automatic gain control and automatic compensation functions and a method thereof are disclosed. The electrodermal activity measurement device according to an embodiment of the present disclosure includes: an amplifier; a plurality of amplification resistors that determine an amplification rate of the amplifier; a compensation resistor connected in parallel with a skin resistance; and a control part that compensates for the resistance value of each of the amplification resistors by using the correction resistor and measures the skin resistance based on the output voltage of the amplifier and the compensation resistance value of each of the amplification resistors. 자동 이득 제어 및 자동 보정 기능을 내장한 피부전도도 측정 장치 및 방법이 개시된다. 본 개시의 일 실시예에 따른 피부전도도 측정 장치는, 증폭기; 상기 증폭기의 증폭률을 결정하는 복수의 증폭 저항들; 피부 저항과 병렬로 연결되는 보정용 저항; 및 상기 보정용 저항을 이용하여 상기 증폭 저항들 각각의 저항 값을 보정하고, 상기 증폭기의 출력 전압과 상기 증폭 저항들 각각의 보정 저항 값에 기초하여 상기 피부 저항을 측정하는 제어부를 포함한다.
