We all know someone with diabetes, and depending on how hard it affects them, there’s a good chance they have to go through the arduous task of checking blood sugar levels daily, but a gadget could at least make this less tiresome.

It’s called the FreeStyle Libre Flash Glucose Monitoring System, and while the name may well be long and complicated, the concept isn’t.

Simply put, the FreeStyle Libre — which is what we’re going to call it just for the sake of keeping things short and maintaining our sanity — is a glucose level scanning patch reliant on the interstitial fluid in your skin that you leave on your body for two weeks, with the sugar monitoring occurring over a contactless electronic reader.


In a way, it’s like having a temporary glucose sensor attached to your body for two weeks of your life, out of sight and out of mind, with the monitoring taken care of simply by waving a gadget over the spot where that patch sits, even with clothes on.

The sensor is even highly water-resistant, meaning you can shower with it attached, and even go for a swim, staying on the body for 14 days before needing to be replaced.


“FreeStyle Libre represents a significant advance in the field of glucose monitoring,” said Professor Stephen Twigg, Head of the Department of Endocrinology at RPA Hospital in Sydney.

“This technology offers a highly convenient and quite painless way to acquire more frequent glucose readings. It enables detailed, actionable glucose profiles that will support people with diabetes across their day, and also encourages a more productive discussion between the patient and their healthcare professional.”


While the technology has obvious potential to do away with the annoy blood prick tests, it also could lead to better diabetes management simply because the information gleaned from the technology should be more detailed overall, with up to eight-hours of history taken in the reading and stores for later on.

The gadget used to capture this is basically a small wireless computer, and this will track patient history, indicating how well someone is going, with hypoglycaemic and hyperglycaemic trends.

And for the experts, this is useful not just because the history is more detailed, but because it will track times when patients aren’t actively checking levels.

“Taking isolated blood glucose readings now and then doesn’t give the whole picture, as levels can markedly fluctuate between such times, including during sleep,” said Professor Twigg.

“The dense FreeStyle Libre glucose data delivered provides a vantage point to link glucose trends to clinical decision-making. It facilitates informed decision making in patient treatment modification, such as in planning carbohydrate intake, insulin therapy dosing, in exercise scheduling, and other self-care behaviours.”
