BIO SIGNAL SENSING APPARATUS

摘要

A bio signal sensing device is provided to improve convenience of a user by sensing the bio signal unconsciously by wearing an earphone or using a cellular phone. A bio signal sensing device includes a first bio signal sensor, a bio signal receiver, and a second bio signal sensor. The first bio signal sensor is attached to an earphone(120) of a cellular phone(100). The bio signal receiver receives the signal from the bio signal sensor and generates the first low data. The second bio signal sensor is attached to the cellular phone or a dongle connected to the cellular phone.
