Development of Palm-Size Blood Glucose Sensor

Diabetes mellitus concerns more than 415 million people worldwide, with increasing tendency. According to the World Health Organization (WHO), more than 80% of the diabetes-related deaths occur in low- and middle-income countries, making this disease a global challenge. True non-invasive glucose measurements procedures are presently not available to the diabetic patient. There have been many different approaches without useful results. We propose a new concept to measure glucose non-invasively based on a high-power mid-infrared laser.

The precision was achieved ±20% in the range from 60 mg/dL to 180　mg/dL of glucose concentrations in vivo monitoring to date. This is in agreement with the requirements of the ISO 15197 standard.
