We Don’t Need to Sugar Coat it — Stick on Tattoos can Measure Blood Sugar for Diabetics

tattoosSweet news for diabetics out there; the never ending days of pin pricks to your fingers may soon be over. Remember how this past summer, you couldn’t leave the house without seeing those shimmering temporary flash tattoos on every 20-something and under girl you passed? What if those gaudy tats were the answer to reading your glucose levels needle-free?

Researchers at the University of California San Diego are working on technology that puts sensors in temporary tattoos in order to read blood sugar levels. The printed electrodes attached to the temporary tattoo paper generate a current through the skin, drawing glucose in the blood close enough for the sensors to read.
So far, the technology has been tested on seven non-diabetic people aged 20-40 years old. They were monitored eating and drinking a carb-heavy meal while stick on tattoos measured their glucose levels. The result was consistent with measurements taken by the traditional finger prick method.

These sensors were built on the same technology that brought us the GlucoWatch back in 2002. Unfortunately, that invention was found to be too irritating to the skin and quickly became irrelevant. The temporary tattoo revises the technology to use lower, non-irritating electrical currents.

Currently, each tattoo is only a couple of cents to replace. The affordability makes the new technology a wonderful option for those on a budget. And the ease of a daily temporary tattoo is greatly preferred to the glucose level reading contact lenses that Google announced last year.

Eventually the tattoos will have Bluetooth technology capabilities to send real time data to the wearer and their physician. We can only hope the manufacturers see the opportunity in making fashion tattoo options, too.
