Abstract

A biosignal detecting apparatus and method thereof are disclosed, including a ring-type main body, and a pair of electrodes configured to be in contact with a finger of a user and to detect a biosignal of the user. An electrode of the pair of electrodes is disposed along an inner surface of the main body.

Claims

1. A biosignal detecting apparatus, comprising:

a ring-type main body;

a pair of electrical electrodes configured to be in contact with a finger of a user and to measure a biosignal of the user, wherein

a first electrical electrode of the pair of electrical electrodes is disposed along a first circumferentially extended portion of an inner surface of the ring-type main body, and

a second electrical electrode of the pair of electrical electrodes is disposed along a second circumferentially extended portion of the inner surface of the ring-type main body; and

at least two interfaces configured to prevent a contact between the first electrical electrode of the pair of electrical electrodes and the second electrical electrode of the pair of electrical electrodes, the at least two interfaces being disposed between each end of the pair of electrical electrodes and including respective insulating materials.

2. The apparatus of claim 1, further comprising:

a reference unit disposed on an outer surface of the ring-type main body to allow a reference position of the biosignal detecting apparatus to be identified.

3. The apparatus of claim 2, wherein the reference unit comprises an ornament.

4. The apparatus of claim 2, wherein the first electrical electrode of the pair of electrical electrodes is disposed along one surface of the inner surface between the reference position and another reference position, opposite to the reference position, and

the second electrical electrode of the pair of electrical electrodes is disposed along another surface of the inner surface between the reference position and the another reference position.

5. The apparatus of claim 4, wherein

the reference unit is disposed on the outer surface of the ring-type main body corresponding to at least one of the reference position and the another reference position.

6. The apparatus of claim 1, further comprising:

an outputter configured to output information on the measured biosignal.

7. The apparatus of claim 1, further comprising:

a communicator configured to transmit information about the measured biosignal.

8. The apparatus of claim 1, wherein the biosignal is an electrical conductance of skin.

9. The apparatus of claim 1, wherein the pair of electrical electrodes are spaced apart within the inner surface of the ring-type main body.

10. The apparatus of claim 1, further comprising:

a processor configured to detect and measure the biosignal, and verify whether a measured value of the biosignal detected is in a reference range;

a communication module configured to transmit information about the detected and measured biosignal to a user terminal in response to the measured value being verified; and

an outputter configured to display the information about the detected and measured biosignal.

11. The apparatus of claim 10, wherein, when the measured value is not within the reference range, the processor controls the biosignal detecting apparatus to apply a physical stimulus to a user.

12. The apparatus of claim 1, wherein

the first electrical electrode and the second electrical electrode collectively cover an entire surface of the inner surface of the ring-type main body except for portions of the entire surface of the inner surface where the at least two interfaces being disposed between each end of the pair of electrical electrodes.
