Objectives

Narrative objectives1

By using the optical measutemnt method, nonndestructive detection system of blood glucose level and other vital signs would be studied practically.
Near-infrared spectroscopy and Fiber Bragg Grating technologies would be appied in these test for subject set.
The stabilities of the measrement system is tested for practical application.

Interventions/Control_1

Approximately 5 micro litter blood should be taken by using a medical needle by each subject. After this operation, invasive blood glucose measuremnt is carried out by the blood glucose meter. This value measured will used as the referenve value of the calibration with the near-infrared spectrum measured at the middle finger oh the subject at the same time.
The pulse wave and the pulse wave velocity of a subject are measred by using the developed fiber senser. At the sametime, his/her blood pressure is monitored by the conventional blood pressure meter.
The correlations between the optical measred values and the conventional method values ere syudied end up to obtaining the calibration models.
The stabilities of the calibration models are tested by the same subject one month after the calibration.

Results

The NIR spectroscopy application to blood glucose measurement was difficult to the practicaltesting, because individual difference is inevitable(621 measuring points from 20 subjects).
Non-invasive blood pressure measurement is expected to be possible with a adequate error 5 mmHg by a calibration of the pulse waves (810 points from 10 subjects).
