From the Institute of Industrial Science, University of Tokyo (UT), comes a novel glucose (blood sugar) monitor. A 1mm diameter "light pipe" like device is injected under the skin, and glow more intense as the glucose levels spike. The fluorescent hydrogel fiber sensor can last up to 140 days, as demonstrated in lab mice. (Hydrogel is made up of 99.9% water with natural and synthetic polymers. The gel is highly absorbent.)
The team from UT boast that this sensor overcomes current enzyme based implanted glucose monitors, resulting in better accuracy, stability, and need for oxygen in the sensing process.
I could see this sensor being a fashion item. Also, it sounds like a beneficial body modification.
