These ingenious tattoos could actually save your life

Tattoos can hold a lot of different meanings. Throughout history, they've been used to communicate status, culture, identity and nowadays merely for fashion. But in the future they could also have functional, medical benefits. Scientists in Germany have developed colour-changing tattoos that could allow diabetic patients and people with other conditions to monitor their health simply by looking at their skin.

The researchers used injectable pigments that change colour when pH, glucose or albumin levels change in the body. The development could allow art and science to be combined, blending tattoo artistry with medical advances. Reddit is abuzz with talk about the possibilities, but for now some significant hurdles remain (if you're looking for inspiration, see our pick of the best free tattoo fonts).
