Researchers at University of Missouri–St Louis in the US have developed a portable, inexpensive and non-invasive blood glucose detector.
The device works by shining a near-infrared light through the finger and calculating the change in the magnitude of light power transmitted through the targeted area to determine the individual’s blood-glucose level.
The device’s small monitor allows pain-free detection of glucose levels without the need for strips or lancets.
Lead researcher Xu Zhi said that the technology provides for detection in just one second, unlike other non-invasive monitors in development.
“There have been 25 years of attempts to create such a non-invasive glucose monitor, and I think we’ve done it,” Zhi said.
According to researchers, future applications of the device could include blood analytes such as cholesterol.
