Wearable Vital sign sensing system for noninvasive blood glucose and blood pressue measurement based on optical measuremnt - Wearable Vital sign sensing system

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).
