Abstract

A brain stimulating system is provided. In some embodiments, the system includes a first electrode configured to supply a minute electric current to stimulate a brain, and a second electrode configured to detect at least one brain signal received from a brain, wherein the second electrode includes a blocking filter configured to block the minute electric current.

Claims

1. A brain stimulating system, comprising:

a first electrode configured to supply a minute electric current to stimulate a brain, wherein the minute electric current is a direct current (DC); and

a second electrode configured to detect at least one brain signal received from the brain, wherein the second electrode comprises a blocking filter configured to block the minute electric current,

wherein the at least one brain signal comprises a DC component and an alternating current (AC) component, and

wherein the blocking filter is configured to block the DC component corresponding to the minute electric current supplied by the first electrode.

2. The system of claim 1, wherein the first electrode comprises an electrolyte layer having an impedance value of 1 kΩ

to 20 kΩ

while the first electrode supplies the minute electric current to stimulate the brain.

3. The system of claim 1, wherein the first electrode comprises:

a solid electrolyte layer configured to be directly contacted with the scalp covering the brain, and a conducting film connected with one side of the solid electrolyte layer.

4. The system of claim 3, wherein the solid electrolyte layer and the conducting film are ductile and configured to be deformed to correspond to a curved surface of the scalp.

5. The system of claim 1, wherein the first electrode comprises a wet electrolyte layer directly contacted with the scalp, and at least one of the first electrode or the second electrode contains a waterproofed protective layer.

6. The system of claim 1, wherein the first electrode comprises:

a first sub-electrode configured to be arranged at a frontal lobe area of the brain to detect a first brain signal responsive to the minute electric current; and

a second sub-electrode configured to be arranged at an area other than the frontal lobe area to detect a second brain signal responsive to the minute electric current.

7. The system of claim 6, the system further comprises a control unit configured to receive the first brain signal and the second brain signal, and extract a third brain signal from a difference between the first brain signal and the second brain signal.

8. The system of claim 1, the system further comprises a control unit configured to control the minute electric current supplied by the first electrode based on the at least one brain signal.

9. A brain stimulating system, comprising:

a first electrode configured to

supply a minute electric current to stimulate a brain, wherein the minute electric current has one of one or more frequency values predetermined based on a user input, and

detect at least one brain signal received from the brain;

a stimulating element configured to control the minute electric current, the stimulating element connected with the first electrode; and

a detecting element configured to receive the at least one brain signal, the detecting element connected with the first electrode,

wherein the detecting element comprises a blocking filter configured to block one or more components of the at least one brain signal, the one or more components have the same frequency value as the one of one or more frequency values predetermined based on the user input.

10. The system of claim 9, wherein the first electrode comprises an electrolyte layer having an impedance value of 1 kΩ

to 20 kΩ

while the first electrode supplies the minute electric current to stimulate the brain.

11. The system of claim 9, wherein the first electrode comprises:

a solid electrolyte layer configured to be directly contacted with the scalp covering the brain, and a conducting film connected with one side of the solid electrolyte layer.

12. The system of claim 11, wherein the solid electrolyte layer and the conducting film are ductile and configured to be deformed to correspond to a curved surface of the scalp.

13. The system of claim 9, wherein the first electrode comprises a wet electrolyte layer directly contacted with the scalp, and at least one of the first electrode or the second electrode contains a waterproofed protective layer.

14. The system of claim 9, wherein the first electrode comprises:

a first sub-electrode configured to be arranged at a frontal lobe area of the brain to detect a first brain signal responsive to the minute electric current; and

a second sub-electrode configured to be arranged at an area other than the frontal lobe area to detect a second brain signal responsive to the minute electric current.

15. The system of claim 14, the system further comprises a control unit configured to receive the first brain signal and the second brain signal, and extract a third brain signal from a difference between the first brain signal and the second brain signal.

16. The system of claim 9, the system further comprises a control unit configured to control the minute electric current supplied by the first electrode based on the at least one brain signal.

17. A brain stimulating system, comprising:

a first device comprising a stimulating element configured to generate a first minute electric current to stimulate a brain and a detecting element configured to measure at least one brain signal received from the brain; and

a second device comprising a control unit configured to receive data containing the at least one brain signal from the first device and manage the received data,

wherein the first device is configured to

analyze a current status of a user,

determine a range of a stimulation magnitude for the user, based on the analyzed status,

generate a second minute electric current corresponding to the determined range, and

stimulate the brain by using the generated second minute electric current, and
