AN ANTI-UV SMART WEARABLE
If you’re the kind of rugged individuals who prefers their smart, health-tracking wearable to come in the form a tattoo instead of a smartwatch, the folks at San Francisco-based LogicInk have you covered. They have developed a smart temporary tattoo, worn on the skin, which changes color as it’s exposed to sunlight.
The tattoo features a design consisting of three concentric rings, created from proprietary inks, which gradually transitions from white to purple. When all three have gone purple, wearers know they’ve reached their daily UV limit.
A TATTOO THAT MONITORS YOUR INSIDES
LogicInk aren’t the only people making smart health-tracking wearables in the form of tattoos. Researchers at Harvard and the Massachusetts Institute of Technology have developed Dermal Abyss, a system of biosensitive inks which change color with changes in the body.
These inks can effectively measure the concentration of glucose, sodium, and pH in the skin’s interstitial fluid, which surrounds cells. The idea of tattoos to measure internal health is still at a relatively early stage, but it could be an immensely helpful (and non-invasive) way of offering up early warnings signs about changes in a person’s health.
