Abstract

A photoplethysmography (PPG) sensor includes: a conductive member contacting with the skin of a user; a luminous element disposed on the conductive member to emit light towards the skin of the user through the conductive member; and a photo detector detecting the light emitted towards the skin of the user.

Claims

1. A photoplethysmography (PPG) sensor, comprising:

a conductive member contacting with the skin of a user;

a luminous element disposed on the conductive member to emit light towards the skin of the user through the conductive member; and

a photo detector detecting the light emitted towards the skin of the user.

2. The PPG sensor of claim 1, wherein the conductive member includes indium-tin oxide (ITO) glass.

3. The PPG sensor of claim 1, wherein the luminous element includes a light emitting diode (LED).

4. The PPG sensor of claim 1, wherein the photo detector is disposed on the conductive member.

5. A photoplethysmography (PPG) sensor, comprising:

a conductive member contacting with the skin of a user;

a luminous element emitting light towards the skin of the user; and

a photo detector disposed on the conductive member to detect the light emitted towards the skin of the user through the conductive member.

6. The PPG sensor of claim 5, wherein the conductive member includes ITO glass.

7. The PPG sensor of claim 5, wherein the luminous element includes an LED.

8. The PPG sensor of claim 5, wherein the luminous element is disposed on the conductive member.

9. A photoplethysmography (PPG) sensor, comprising:

a conductive member contacting with the skin of a user;

a luminous element disposed on the conductive member to emit light towards the skin of the user through the conductive member; and

a photo detector disposed on the conductive member to detect the light emitted towards the skin of the user through the conductive member.

10. The PPG sensor of claim 9, wherein the conductive member includes ITO glass.

11. The PPG sensor of claim 9, wherein the luminous element includes an LED.

12. A photoplethysmography (PPG) sensor, comprising:

a luminous element emitting light towards the skin of a user;

a first conductive member disposed on one surface of the luminous element to contact with the skin of the user;

a photo detector detecting the light emitted towards the skin of the user; and

a second conductive member disposed on one surface of the photo detector to contact with the skin of the user.

13. The PPG sensor of claim 12, wherein the conductive member includes ITO glass.

14. The PPG sensor of claim 12, wherein the luminous element includes an LED.
