Abstract

A mobile terminal capable of measuring a biological signal is provided. The terminal comprises a terminal body; an electrode for human body earth or system reference, placed on an outer surface of the terminal body so as to be contactable with the skin of a user of the mobile terminal; and differential electrodes. The measured biological signals include an electromyography signal and an electroencephalogram signal. The differential electrodes can be external to the terminal body and be connected via lead lines to the terminal body.

Claims

1. A mobile terminal capable of measuring a biological signal, comprising:

a terminal body;

an electrode for human body earth or system reference, placed on an outer surface of the terminal body so as to be contactable with the skin of a user of the mobile terminal; and

differential electrodes.

2. The mobile terminal as claimed in claim 1, wherein

the biological signal is an electromyography signal or an electroencephalogram signal.

3. The mobile terminal as claimed in claim 1, wherein

the differential electrodes are external to the terminal body and connected via lead lines to the terminal body.

4. The mobile terminal as claimed in claim 1, wherein

the differential electrodes are placed on the outer surface of the terminal body so as to be contactable with appropriate portions of the skin of the user for measuring the biological signal.
