Tattoos get smart ink
WE have heard about the good oil, but how about the good ink?
Harvard and MIT researchers have turned body art into medical technology by developing tattoo ink capable of monitoring health.
The smart ink changes colour if the wearer is dehydrated or if blood sugars rise and fall in diabetics.
The bio-sensitive inks developed at Harvard have combined with traditional tattoo artistry as a way to overcome some of the limitations of current biomedical monitoring devices which are battery dependent.
