Designer Tobias Förtsch has created a virtual prototype for a noninvasive (and nonexistent) glucose monitor that seems to be inspired by iPod MP3 players. The only problem, of course, is that the search goes on for technology that can properly do glucose measurements without having people prick themselves for a drop of blood.
From Yanko Design:
The small device measures sugar levels using a display with an LED scale between a low result and a high result in different colors. Low sugar levels are shown in red. A normal level appears in white white and a high level goes orange. It stores the result and transfers it via bluetooth to a mobile phone and computer so your doctor has instant access.
The flexibility comes in how you measure your levels. A detachable sensor clips to your earlobe and gives you auditory feedback when your levels get to high. The same info gets transfered to your phone and computer. If your blood chemistry gets out of hand, a call can be made via your mobile to alert your doctor.
