Telemed noninvasive glucose blood level measuring by near infrared light

Nowadays, there are about 100 million diabetes patients and increasing in every day. One of the procedures to diagnose this disease is to measure the blood glucose level. The technology of blood glucose measurement that normally use is invasive to the patient by punctured the fingertip and collect the drop of blood to test. Thus, diabetes patients have a pain in several times a day and in one test. They must buy the strip test and needle. So, the little cost in one day will become the huge cost in one year. And that is the reason to develop a non-invasive way to monitor the blood glucose level that has lower cost and risk of infection for them. This paper presents a new noninvasive blood glucose measuring method by near infrared light 940nm wavelength as emitter transmitting though finger for receiving PPG signals to determine glucose level of blood. Using 12 samples for regression fit curve finds relation between maximum value and minimum value of PPG signals and blood glucose level (mg/dl). Results give accuracy 95.13% which is in high range for accuracy. In this device also can connect wi-fi to store data.
