Scientists successfully tested a portable non-invasive glucometer

At the end of 2021 scientists tested a portable personalized non-invasive glucometer, which was developed at the NTI Competence Center "Sensorica" based on MIET. The tests were carried out in the laboratories of the Center. The next stage - clinical trials - is scheduled for 2022.

The device allows you to measure the concentration of glucose in the blood without taking it. The glucometer is based on diffuse reflectance spectroscopy. It contains a miniature infrared laser that irradiates human tissues. During the propagation radiation is absorbed by glucose and weakens. The lower the intensity of the radiation reflected from the tissues registered on the photodetectors, the higher the concentration of glucose in the tissues and in the blood.

The glucometer is implemented in the form of a small block; it can be fixed on the wrist using a bracelet. A patient should continuously wear the device for greater effect. It allows to measure the concentration of glucose in the blood every 5 minutes, build a graph in a mobile application and send data to the doctor.

“The key characteristic is the measurement inaccuracy, which, according to the test results, averaged from 18.5 to 19.9%. This accuracy is sufficient to ensure continuous monitoring of glycemia, registering a sharp drop in glucose levels for taking timely measures,” said Kirill Pozhar, the leading developer of the project, associate professor at the Institute of Biomedical Systems, an employee of the Center.

The non-invasive glucometer is planned to be launched onto the Russian market in 2025-2027.
