Researchers at the Massachusetts Institute of Technology and Harvard Medical School recently co-founded a research program called Dermal Abyss to replace traditional tattoo inks with "biosensors." The sensor ink passes through the color change, reflecting the user's blood sugar status, acidity and so on, allowing the user to grasp the details of the body every minute.
Smart health wear devices like smart watches and bracelets have some common problems: they don't really stick to you to track health, they must be “as much as possible†to capture your health through the support of multiple hardware technologies.
For example, multi-axis sensors, heart rate sensors, etc., but not always attached to your skin, we can only rely on machine perception, wireless connectivity and a certain degree of battery life to maintain machine operation.
That's where Harvard Medical School and MIT think they can serve the public. They have jointly developed a smart tattoo (Tattoo) that effectively puts health sensors on the user's skin without the need for electricity and networking. connection. Ali Yetisen, a postdoctoral researcher at Harvard Medical School, said: "We are thinking about what is possible with future wearables."
Tattoo inks react to the chemical composition of the user's tissue fluid to detect blood status. When the athlete is dehydrated, the green ink becomes more intense, and when the other green ink turns brown, the blood sugar level of the diabetic patient rises.
Biosensor ink developed by Dermal Abyss researchers.
How is it actually displayed? For example, the most painful thing for diabetic patients is to puncture blood for blood glucose tests every day. Because long-term exposure to high or low blood sugar in diabetic patients can easily lead to complications, blood glucose self-monitoring becomes home care for diabetic patients. And the most important part of self-management.
But with the help of the Dermal Abyss program in the future, they only need to visually observe the changes in the tattoo. When blood sugar rises, the tattoo turns from blue to brown. Dehydration is also a common health problem compared to diabetes, and Dermal Abyss can also monitor changes in ink color. As the salt content increases, the tattoo becomes greener and effectively monitors other physical signs other than diabetes.
The tattoo on the body changes with the physical condition: sodium content, acid value, glucose level and so on.
Dermal Abyss is different from other tattoos we have seen before. This kind of "inorganic sensor ink" does not always appear. If it is too conspicuous, the smart tattoo ink can be "transparent" unless there is special light. Otherwise, it will not develop color in general, so it is not necessary to explain the meaning of the tattoo to others, and the trouble with some explanations. Nan Jiang, a postdoctoral researcher at Harvard Medical School and Brigham and Women's Hospital, said: "This tattoo ink has been tested and will not spread to other dermal layers and will not fade. As a conceptual experiment, we will further improve it. ."
Smart Tattoos can be analyzed through a smartphone app and then analyzed to tell you exactly what the tattoo (color change) represents (physical condition). Nan Jiang further talked about: The Smart Tattoo Program (Dermal Abyss Project) can stimulate the "joint creativity" between scientists and artists, not only to bring breakthroughs in scientific research and technology, but also to properly solve the problem of general people's tracking of health.

If you have a long-term reason to monitor your health, then get tired of having to put other smart devices on your body in addition to your phone, so you can accurately monitor and digitize your health. This tattoo can make you feel much more comfortable. The "user experience" is undoubtedly more direct and seamless.
In the future, if Dermal Abyss gets wider support and further expands the research scale, then we can expect that smart tattoos will show more body values ​​and quantify more health details besides blood. From that time on, humans may not need to wear other healthy wearable devices. The concept and thoughts of the Dermal Abyss plan may have the potential to redefine the future of smart wearable devices.
