Non-invasive device could end daily finger pricking for people with diabetes

A new laser sensor that monitors blood glucose levels without penetrating the skin could transform the lives of millions of people living with diabetes.

Currently, many people with diabetes need to measure their blood glucose levels by pricking their fingers, squeezing drops of blood onto test strips, and processing the results with portable glucometers. The process can be uncomfortable, messy and often has to be repeated several times every day.

The new technology, developed by Professor Gin Jose and a team in the Faculty of Engineering at the University of Leeds, uses a small device with low-powered lasers to measure blood glucose levels without penetrating the skin. It could give people a simpler, pain-free alternative to finger pricking.

The technology has continuous monitoring capabilities making it ideal for development as a wearable device. This could help improve the lives of millions of people by enabling them to constantly monitor their glucose levels without the need for an implant.

It is also good news for healthcare providers as it could provide a simpler and cheaper alternative to both of the current methods
