Revolutionary radiation-sensitive plastic (trademark "Scintirex") with a performance superior to plastic scintillators used for measuring radiation and enabling a major reduction in production costs : NIRS
Sintirex is a recycled PET plastic based plastic scintillator, which basically means the chunk of plastic glows in the dark if hit by radiation. So you put it in a sealed case with a simple optical sensor like a cheap CCD to make a crude but effective low cost radiation detector. Apparently it should be possible to make portable detectors that currently cost $500 for around $100 or less now.

"Prescription" Tattoos Could Monitor Blood-Glucose Levels in Diabetics | Ecouterre
Nice non-invasive alternative to pricking your finger all day to get blood glucose readings. You could potentially compact the necessary reader equipment to a watch sized device, and put the invisible tattoo on both wrists.
