A “non-invasive” device which allows people with diabetes to monitor blood glucose levels without pricking their skin has been developed.

The portable creation uses microwaves and can be discreetly stuck to the skin.

Speaking to the BBC, Professor Adrian Porch from Cardiff University’s School of Engineering who developed the device, said: ” It will help with the management of the condition.

“Conventional methods of monitoring blood glucose require the extraction of blood. Our device is non-invasive – it does not require the extraction of blood apart from the initial calibration.”

The team behind believe the device believe it could make life easier for the millions of people who have diabetes around the world.

The project has received £1m in funding from the Wellcome Trust up to now, and has already been used in clinical trials in patients.

Further funding is needed to allow the device to reach the commercial market. 

One of the big problems with patients measuring their glucose is they don’t like pricking their finger, so there’s a lot of interest

The device, which attaches to the body via sticky adhesives, uses microwaves to measure glucose levels, sending the resulting data to a computer or mobile app.

Professor Porch added: “It uses microwaves, but the levels are very, very low. Nowhere near the levels used in domestic cooking. Think about a mobile phone, we’re about a thousand times less than that level.”

There are 3.5 million people diagnosed with diabetes in the UK, with an estimated 549,000 more who have the condition, but do not know it.

Professor Stephen Luzio, of Swansea University’s College of Medicine, carries out clinical research into diabetes.

He has overseen trials on about 50 people who have trialled the device and he told the BBC that “patients are very keen on this. One of the big problems with patients measuring their glucose is they don’t like pricking their finger, so there’s a lot of interest”.
