Abstract

A sensor for measuring biometric information includes a biometric electrode sensing biometric information in a state in which the biometric electrode is in contact with a surface of the skin; and a signal line transmitting the sensed biometric information, wherein the biometric electrode is printed on an inner surface of an item of clothing that comes into contact with a human body.

Claims

1. A sensor for measuring biometric information, the sensor comprising:

a biometric electrode sensing biometric information in a state in which the biometric electrode is in contact with a surface of the skin; and

a signal line transmitting the sensed biometric information,

wherein the biometric electrode was formed by printing a mixture solution, obtained by mixing a carbon nano-tube (CNT) dispersion with textile paint, on an inner surface of the item of clothing that comes into contact with a human body, and

wherein the CNT dispersion was prepared by mixing 3.0wt. % of CNT and an isopropyl alcohol (IPA) solvent, by being stirred by a stirrer for 0.5 to 4 hours, by being aged for 24 hours, and a supernatant was subsequently removed using a centrifugal separator.

2. The sensor of claim 1, wherein the signal line is formed by printing the mixture solution on an inner surface of the item of clothing.

3. The sensor of claim 2, wherein the textile paint is printed on a surface of the signal line.

4. The sensor of claim 1, further comprising:

a snap button provided at an end portion of the signal line; and

a signal processing device having a detachable recess formed to be attached to or detached from the snap button, and receiving biometric information transmitted through the signal line.

5. The sensor of claim 4, wherein the signal processing device includes:

an amplifier amplifying the received biometric information;

a filter filtering the amplified biometric information; and

a communications module wirelessly transmitting the filtered biometric information outwardly.

6. An item of clothing comprising:

a sensor for measuring biometric information including a biometric electrode sensing biometric information in a state in which the biometric electrode is in contact with a surface of the skin and a signal line transmitting the sensed biometric information,

wherein the biometric electrode was formed by printing a mixture solution, obtained by mixing a carbon nano-tube (CNT) dispersion with textile paint, on an inner surface of the item of clothing that comes into contact with a human body, and

wherein the CNT dispersion was prepared by mixing 3.0wt. % of CNT and an isopropyl alcohol (IPA) solvent, by being stirred by stirrer for 0.5 to 4 hours, by being aged for 24 hours, and a supernatant was subsequently removed using a centrifudal separator.

7. The item of clothing of claim 6, wherein the signal line is formed by printing the mixture solution on an inner surface of the item of clothing.

8. The item of clothing of claim 7, wherein the textile paint is printed on a surface of the signal line.

9. The item of clothing of claim 6, wherein the sensor further includes:

a snap button provided at an end portion of the signal line; and

a signal processing device having a detachable recess formed to be attached to or detached from the snap button, and receiving biometric information transmitted through the signal line.

10. The item of clothing of claim 9, wherein the signal processing device includes:

an amplifier amplifying the received biometric information;

a filter filtering the amplified biometric information; and

a communications module wirelessly transmitting the filtered biometric information outwardly.

11. The item of clothing of claim 6, wherein the item of clothing is formed of a material having elasticity.
