Wearables for diabetes, more get thinner on a ‘smart skin’ diet

[grow_thumb image=”https://telecareaware.com/wp-content/uploads/2016/03/BG-cuff.jpg” thumb_width=”150″ /]A team from the Seoul (South Korea) National University, University of Texas-Austin and wearable health sensor developer MC10 [TTA previous articles] have developed a translucent, thin graphene ‘cuff’ with sensors for blood glucose and a not-quite-complete metformin delivery mechanism for those with Type 2 diabetes. The graphene is ‘doped’ with gold to have it transmit blood glucose readings inferred on mechanical strain, skin temperature, and chemical composition of sweat. The mobile app calculates the metformin medication dose needed and the wristband administers it through an array of microneedles. This would not be a semi closed-loop system (dubbed here a ‘robopancreas’) which Type 1 diabetics now can use for insulin delivery, as there’s a delay in sensing and delivery. It also cannot in present form correct for excessively low blood glucose. IEEE Spectrum, Nature (abstract) Hat tip to former TTA Ireland Editor Toni Bunting

Google’s blog and a single interview they granted to the Associated Press have confirmed the earlier rumor on a blood glucose-measuring contact that first appeared last Friday [TTA 10 January; item from FierceMedicalDevices in the 4th paragraph, Google’s meeting with FDA on a powered contact lens]. The AP article also confirmed its genesis in University of Washington/NSF research. The Google lens under development might have tiny LED lights that visually advise the wearer on their glucose levels, as well as transmit the information via a wireless chip. Last week’s speculation was on a Google Glass-like display à la iOptik.

Research specifically directed towards continual monitoring of the blood glucose in tears has been ongoing and other companies have developed powered lenses. A key question is the equivalence and accuracy of monitoring tears versus blood. (more…)
