bloodless diabetic testing via temporary tattoo?

New Atlas that has an article about a 'temporary tattoo' that is used to measure blood sugar level in a way that does not require pricking ones finger. As a diabetic, I have an interest in such a device.

The source of the article is University of California, San Diego.

I look forward to the day that I won't have to prick my finger to check my blood sugar level. I think this has a lot of potential. I hope it is successful. 

Live Science has an article on it.
