Abstract

A wearable device, a charger, and a method for estimating absorbance of the wearable device are provided. The wearable device includes a spectroscope configured to emit a first light to a reference material of a charger, measure an intensity of the first light reflected from the reference material, emit a second light to a skin of a user, and measure an intensity of the second light reflected from the skin of the user; and a processor configured to determine absorbance of the skin of the user based on the intensity of the first light and the intensity of the second light.

Claims

1. A charger of a wearable device which comprises a spectroscope, the charger comprising:

a reference material arranged or coated on a side of the charger facing a light emitting side of the wearable device when the wearable device is installed on the charger.

2. The charger of claim 1, wherein the reference material is a diffused reflection material.

3. The charger of claim 2, wherein the reference material comprises at least one of barium sulfate (BaSO₄) and polytetrafluoroethylene (PTEF).

4. The charger of claim 1, further comprises:

a lower body on which the wearable device is placed; and

a support body configured to support so that the wearable device is not inclined.

5. The charger of claim 4, wherein the lower body has a structure in which the wearable device is naturally located in a chargeable region when the wearable device is placed.

6. The charger of claim 5, wherein the lower body has a cylindrical shape and has a structure in which its edge portion is higher than its center portion.

7. The charger of claim 5, wherein the support body is formed at a right angle with the lower body.

8. The charger of claim 4, wherein the reference material arranged or coated on the support body.
