Get Inked For Life! These Tattoos Will Monitor Your Vitals With Smart Sensors Injected Into Your Skin.
Scientists are working on sensors that are to be injected into the human skin so that blood glucose levels and other factors can be monitored.
A team at the Technical University of Munich in Germany identified three chemical sensors that change color in response to biomarkers — glucose, albumin, or pH — in the fluids between the body’s cells.
One sensor turns green with albumin presence and low levels of this could point at kidney or liver failure. Another sensor changes from yellow to dark green with an increase in the glucose levels. High levels of glucose could indicate poorly managed diabetes. The third one turns from yellow to blue when the pH level in your body shifts from slightly acidic to alkaline.
While the sensors have so far only been tested on pig skin, it seems to be working well and more testing is expected to be done. Tattoos could also be a way for us to monitor the effect of the environment on our body. A team at the University of Colorado Boulder has come up with a tattoo sensor that only appears on the skin when exposed to UV light, alerting people when they need another coat of sunscreen.
Other ideas include sensors that are visible at certain temperatures or one that could conduct electricity. One debatable point is how enthusiastic would one be to get a tattoo, keeping in mind it contributes to both aesthetic and medical factors. For those who are not comfortable with permanent tattoos, temporary options may be on the way.
