PORTABLE DEVICE FOR MEASURING BIOLOGICAL SIGNAL

摘要

PURPOSE: A portable terminal for measuring a bio signal is provided to control quantity of motion of a user by detecting the bio signal through an electrocardiogram detector accurately. CONSTITUTION: An earphone bio signal detector(125) includes an earphone electrocardiogram sensor(130). The earphone electrocardiogram sensor includes a first electrocardiogram electrode. The first electrocardiogram electrode is arranged in a right ear of the user. A bio signal measuring terminal(200) includes a brachial electrocardiogram sensor(140). The brachial electrocardiogram sensor has a second electrocardiogram electrode. The second electrocardiogram electrode is arranged in the left forearm of the user. The electrocardiogram of the user is measured by detecting the potential difference between the brachial electrocardiogram sensor and the earphone electrocardiogram sensor.
