Researchers at MIT and Harvard created a Bio sensitive ink that will indicate your health stats. They are looking forward to using these “smart” tattoos that could be able to conquer the constraints of regular health wearable technical and make human skin an interactive surface.
Smartwatches, connected bracelets, and activity trackers like Apple’s hottest series of Apple Watch are changing the way of managing our health. They have grown to be far better as health monitors using the system of sensors, including pedometers, heart rate monitors, sleep quality analyzers, and workout-related apps.
However, their use continues to be limited due to some factors, such as their power supply life and their dependence over a constant Web connection. Apple solved that previous one with the Apple Watch 3. Smart tattoo designs, on the other hand, are poised to omit these issues, while delivering real-time insights into one’s health. If e-tattoos have taken a long time to arrive, it isn’t for want of hoping by researchers who are helping these wearables get the body real property they deserve.
Last year, MIT Media Laboratory presented its wearable, called DuoSkin, developed with Microsoft Research using gold leaf. DuoSkin is an on-skin interface associated with an e-tattoo that changes the skin into a touchpad. It could, for example, remotely control a telephone or provide information on body’s temperature by changing colour somewhat like a mood ring.
MIT has recently partnered with another university to imagine smart tattoos that require no power source or Wi-Fi to function, unlike other wearables and connected objects. Researchers at MIT Media Laboratory and Harvard Medical College have developed a smart tattoo printer ink that changes colour to indicate blood sugar levels or dehydration levels.
“We were thinking: New technologies, what is the next generation of wearables?” said HMS’ Ali Yetisen, one of the ink developers. “And so we came up with the idea that we could incorporate biosensors in the skin.” To build “Dermal Abyss“, unlike normal tattoo ink, the MIT and HMS research team used biosensors that change their colour in reaction to variations in the interstitial liquid located between epidermis cells.
There would be an associated code to interpret each colour the printer ink takes. Researcher’s explored four detectors that react to three biochemical reactions: The first sensor passes from blue to brownish depending on the increase in sugar level. The pH sensor will go from purple to pink. Another pH sensor turns fluorescent under UV light. Last but not least, the sodium sensor also reacts to UV using fluorescence.
Researchers provided some considered to the aesthetic aspect of their creation as well because Dermal Abyss blends “advances in biotechnology with traditional methods in tattoo artistry.” This system requires no battery, so the tattoo can stick to the skin for a long time without problems, and if the user for whatever reason no longer would like the tattoo, it could be removed easily. Dermal Abyss ink is still at the proof-of-concept stage, so will probably take a couple of years before it’s practical for the commercial market.
