> 2. Insulin sensor. How would it detect/monitor insulin levels? Have a needle on the back?

  1. That appears to still be at the prototype stage (as of that post in Jan?). 2. It goes right on your freakin' eye, and apparently measures your tears. So.. I guess if you strapped a watch to your eye it might work?

  No they stick a piece of glass in your eye. Seriously: that is highly experimental technology, based on an experimental technique, in a very specific part of the body. It is not remotely trivial to do that on regular skin. I know in particular because a friend just submitted his PhD on the use of microdermal patches for blood analysis: the short answer is, it might work, but no one actually has any idea how the levels of things they detect relate to what the normal blood levels are which our current health science is based on. EDIT: Also no one has any idea of what the sensor longevity would be. For new stuff like this, the answer tends to be single-use.

  Now that is seriously cool. I imagine patented heavily. Are they actually available, or still in the trial phase? (I couldn't tell from the site)

    These ones are still on trial (according to their latest news they are currently on FDA testing and aim for commercialisation in 2015~2016) but others already have bloodless glucometers for sale (e.g. http://www.cnoga.com http://www.cnoga.com are available but not in the US because FDA testing ongoing). Those blokes were just the first ones I found.
