Her Tattoo Suddenly Changed Colors And The Reason Why Is Really Cool


For people with Type 1 and Type 2 diabetes, checking insulin levels is just part of everyday life.

And it can be seriously stressful. But what if there was a way to keep track of your health without the use of expensive devices and testing strips? Well researchers at Harvard and MIT have come up with a monitoring system that mimics body art. These color-changing tattoos can monitor not only diabetes, but other conditions as well.

With the combined efforts of the two universities, researchers have developed a biosensing tattoo using DermalAbyss ink that changes color in response to things like blood sugar levels.

DermalAbyss ink is also able to keep track of pH levels, as well as sodium and glucose in your bloodstream.

Too much glucose in your system, for example, results in the tattoo turning brown, while too much sodium will turn the body art green.

And if you’re experiencing a change in your body’s pH levels, your tattoo will change to shades of purple or pink.

The ink is so sensitive, in fact, that it monitors your interstitial fluids down to the lining of the cells.

The ink has only been tested on pig skin and human trials are pending.

DermalAbyss: Possibilities of Biosensors as a Tattooed Interface

Project Page: https://www.media.mit.edu/projects/d-Abyss/overview/



Can tattoos embrace technology in order to make the skin interactive?



The Dermal Abyss is a proof-of-concept that presents a novel approach to biointerfaces in which the body surface is rendered an interactive display. Traditional tattoo inks were replaced with biosensors whose colors change in response to variations in the interstitial fluid. It blends advances in biotechnology with traditional methods in tattoo artistry.



We developed four biosensors, reacting to three biochemical information in body fluid and changes colors: The pH sensor changes between purple and pink, the glucose sensor shifts between blue and brown; the sodium and a second pH sensor fluoresce at a higher intensity under UV light.



The Dermal Abyss creates a direct access to the compartments in the body and reflects inner metabolic processes in a shape of a tattoo. It could be used for applications in continuously monitoring such as medical diagnostics, quantified self, and data encoding in the body.



Preliminary evaluation was done in an ex vivo pig skin model.Several injections in the skin were done in order to understand the visibility and functionality of the biosensors.
