Tattoo Tech, Carson Bruns, Bruhns discussed on Kottke Ride Home
Tend to have become increasingly common over the last few decades and accordingly, the stigma surrounding them has worn off quite a bit as well. It's still there of course, especially in older generations in certain cultures. But what if you could defend your tattoo by saying it's for medical purposes. Tattoos that can indicate biochemical changes in your body as warning signs for larger conditions have been in development by various teams of scientists over the last several years. Carson bruns a chemist artist and assistant professor at the University of Colorado. Boulder has been working on tattoos that detect UV lights and also served as the first human test subject for them. But before I dive more into bronzes specific work, here's a quick summary of recent developments quoting the conversation in two thousand seventeen researchers tattooed pigskin, which had been removed from the pig with molecular bio sensors that use color to indicate sodium glucose or. Ph levels in the skins fluids in two thousand, nineteen team of researchers expanded on that study to include protein sensing and developed smartphone readouts for the tattoos. This year they also showed that electrolyte levels could be detected with fluorescent tattoo sensors in two thousand eighteen biologist developed a tattoo made of engineered skin cells that darken when they sent an imbalance of calcium caused by certain cancers they demonstrated the cancer detecting tattoo in living mice and quotes. While all of those projects detect biomedical changes within a person Brinson, his team are working on the detection of external changes mostly UV exposure as a warning sign for skin cancer quoting bruns. In the conversation, we developed an invisible tattoo ink that turns blue only in UV light alerting you when your skin needs protection. The tattooing contains a UV activated die inside of Plastic Nanno capsule less than Micron in diameter or thousandth of a millimeter about the same size as an ordinary to pigments. The Nano capsule is needed to make the color changing tattoo particles large enough if tattoo pigments are too small, the immune system rapidly clears them from the skin and the tattoo disappears. They're implanted using tattoo machines in the same way as regular tattoos but they last for only several months before they start to degrees from UV exposure and other natural processes and fade requiring a booster tattoo end quote. The team is also developing UV protective tattoos that would essentially act as long lasting sunscreen by absorbing the UV light that penetrates the skin. While that may sound like a lot of pain to endure for how much surface area that would have to cover to be effective bruhns also notes that scientists have been working on needle free tattooing methods using microscopic ink droplets fired into the skin. And Tattoo Tech is going in even more directions. There's epidermal electronics or wearable electronic tattoos that would do things like quote sense electro physiological signals like heart rate and brain activity or monitor hydration and glucose levels from sweat and quotes. But there's also non-medical uses like quote controlling mobile devices, for example, Shuffling Music playlist at the touch of a tattoo or for luminescent body art that lights up the skin and quotes. Bruhns, notes that color changing tattoos that can be programmed with electromagnetic signals will change the game on tattoos. You could have a tattoo that's visible when you're out with friends but turn it off for work. All of this is not completely without risk however, even ordinary tattoo pigments currently in use are unregulated by the FDA hopefully as new tech is being developed in labs, there will be some level of caution in oversight being exercised, but the long term effects of micro and Nano implants is yet to be studied..
