Discovery News just came out with an article about a new type of ink tattoo which can monitor sugar levels of diabetics. This is less painful than the usual blood glucose test used. Read more about it here.
Another report describes the process as having a sensor that would be injected into the skin’s surface layers — actually shallower than tattoo ink. A fluorescence monitor, resembling an optical mouse, would then be used to measure the light emitted by the tattoo.
Aside from monitoring glucose, there are possible applications to monitor sodium levels, which can measure hydration. This would most likely lead to the tattoo becoming a mandatory style for club-going ecstasy users.
