MIT engineers<\/strong> have developed a new method that makes blood sugar measurement needle-free<\/strong> by applying near-infrared light<\/strong> to the skin. The technology is reported to offer high accuracy<\/strong>.<\/p>\n\n\n\n

The new generation glucose measurement system<\/strong> developed by the MIT team<\/strong> offers a technology that could eliminate the necessity of finger pricking<\/strong> and using subcutaneous sensors<\/strong> for diabetic patients. Researchers are working on a method that can measure blood sugar levels<\/strong> solely using light waves<\/strong>. While the initial prototype is still relatively large, it has the potential to shrink to the size of a smartwatch<\/strong>.<\/p>\n\n\n\n

Blood sugar tracking<\/strong> is of vital importance in diabetes management<\/strong>. For decades, these measurements were generally performed via finger pricking<\/strong>. Although wearable glucose monitors<\/strong>, which have become widespread in recent years, provide continuous measurement<\/strong>, the sensors placed under the skin<\/strong> must be replaced every 10-15 days and can lead to issues such as irritation<\/strong>.<\/p>\n\n\n\n

Can be detected with light<\/strong> As a solution to this problem, MIT researchers<\/strong> are utilizing the Raman spectroscopy<\/strong> method. This technique determines the glucose level<\/strong> by analyzing Raman signals<\/strong> generated from the interaction of light sent into tissues with molecules. In 2010, the team demonstrated that they could measure glucose levels indirectly with this method, but the device was not very practical for daily use<\/strong>.<\/p>\n\n\n\n

With a new approach developed in 2020, signals originating from other molecules in the skin were filtered out, enabling the direct detection of the glucose signal<\/strong>. The device, initially the size of a printer, has been reduced to the size of a shoebox<\/strong> through optimizations. At the core of this downsizing lies the discovery that only three of the approximately one thousand bands in the Raman spectrum<\/strong> are sufficient for glucose measurement<\/strong>. Furthermore, measurements are completed in about 30 seconds<\/strong>, and the accuracy level<\/strong> is on par with existing commercial wearable<\/a><\/em> glucose monitors<\/strong>.<\/p>\n\n\n\n

Tests have begun<\/strong> Researchers are testing a mobile phone-sized prototype<\/strong> of the device with healthy and prediabetic volunteers<\/strong>. In the future, the goal is to shrink the device to the size of a watch<\/strong> and ensure it can perform reliable measurements<\/strong> on different skin tones<\/strong>. The MIT team<\/strong> emphasizes that high-accuracy<\/strong> and completely needle-free glucose measurement<\/strong> will make a significant difference in the quality of life<\/strong> for diabetic patients.<\/p>\n\n\n\n
