Measuring physiological indices with Arduino

Abstract

Measuring physiological responses using Arduino microcomputers has become increasingly popular in recent years. This technical note describes making circuits on a breadboard to measure three major psychophysiological research indicators: electrocardiogram, electromyogram, and skin conductance. This note also explains how to program and measure these indices using the Arduino development environment. An advanced example of wireless measurement utilizing a microcomputer that supports Bluetooth and Wi-Fi communication is also presented. The measurement of physiological indices using handmade circuits makes the system more affordable and offers additional advantages, including a more precise understanding of the indices and flexible experimental designs. These methods are expected to develop new possibilities for psychophysiological measurements.
