It relates to a device for estimating blood sugar by using a photoelectric pulse wave signal. According to an embodiment, the blood sugar estimation apparatus acquires a pulse wave sensor measuring a pulse wave signal from a subject and two or more points of the pulse wave signal waveform, and extracts features based on time of the obtained two or more points to estimate blood sugar It may include a processor. In addition, according to another embodiment, the blood sugar estimation apparatus may obtain a more accurate blood sugar estimation value by further considering the blood sugar value estimated using the metabolic model to the blood sugar value estimated using the photoelectric pulse wave signal. |
