Staying healthy is a 24/7 operation. You’ve constantly got to check in with yourself, ensuring that you’re making the right decisions about everything from what you do and how you think to what you eat. There are doctors and nutritionists and therapists and oodles of other healthcare professionals to help you stay on track (as well phone apps and gear), and you’re probably constantly on the lookout for healthful tips and tricks. We all are.

Well, there’s a new invention that’s bound to help your health: a colour-changing tattoo straight out of a sci-fi movie! Now that’s a great reason to get a tattoo.

Katia Vega, a researcher at Massachusetts Institute of Technology, is developing an artful yet scientific tattooing method that uses colour-changing ink to monitor the body’s pH, sodium and glucose levels.

By swapping the regular tattoo ink with biosensors that change colour when they detect triggers in the fluid surrounding cells, Vega and fellow researchers are hoping that their “Dermal Abyss” tattoo ink will one day help people remain in optimal health. For example, a diabetic with a glucose sensitivity could see the colour of the tattoo change immediately and take that as an indication to further check their sugar levels. Why prick a finger over and over again when you could just get a tattoo?

It’s like a mood ring, only you can’t take it off, and instead of predicting your emotional state, it changes from purple to pink to indicate pH change, from blue to brown for glucose, and becomes fluorescent under UV light when the sodium and secondary pH sensors are activated.

So far, it’s still being tested and developed, but the results have been very promising. You may want to think of a meaningful tattoo design in the mean time.
