hypo unawareness bracelet

I'm a final year textile design student at Edinburgh College of Art.
I'm researching into innovative textile fibres and my concept is to make a unisex band/bracelet with would change colour or heat up when your blood sugars dropped significantly. I'm aiming it more towards people with hypo unawareness, however, could be useful for others too.. I'm still doing lots of research into thermochromatic dyes, heat reactive fabrics and maybe metals but basically I need some feedback about how useful this may be in alerting people before they get serious hypos. Intending the design of it to be also quite stylish so it has a normal appearance and not drawing too much attention from others. Thinking it may allow people with hypo unawareness more freedom to do day to day activities without the worry? let me know what you think and if you have any suggestions for me!!

i have hypo awareness and tend to get a bit hot and flustered but obviously it's different for everyone. I thought about the perspiration thing also, I'll need to look into whether people with hypo unawareness have zero symptoms or just no physical symptoms they are aware of. I'm just wondering whether this bracelet would have a chip reader inside and then the user would have a tiny sensor placed under the skin, kind of like with insulin pumps, and the sensor could read low sugar levels, signalling the bracelet to change colour/heat up. Really my project right now is looking into whether such an accessory would be useful for those with hypo unawareness? Most of the feedback i've had is positive. Medic alert have bands which indicate a person with diabetes, I find them a bit unsightly though. I would say for what i'm doing, I wanted to create something that looked great without immediately spelling out a disability, catering to the emotional side of diabetes. I for instance, when growing up, just wanted to be like my friends, so creating something more subtle wouldn't draw unwanted attention from others but this would still serve a use in alerting people to hypos in a more calming fashion using colour. Obviously I'm thinking from a textile designer point of view here. Here is an example of another artist I have looked at who creates colour changing blood sugar monitors for type 2 diabetic people : http://mickaelboulay.fr/index.php?/meas ... s/content/
I love it but wouldn't find it accurate enough for me.

thanks for your feedback! no worries I welcome positive as well as negative! This is exactly what I need to find out. As I said above.. maybe it should be a chip placed under the skin which has direct contact with the blood and picks up a falling sugar level.. Its only a one week project about innovation so the logistics aren't my main worry at the moment, just research into whether theres a market for such a device. Which I think there may be as it seems all these links are suggesting that things in that past haven't worked?
