Aside from the design you choose, another part of showing off your tattoo with pride is reminding others of all the pain you went through to get it. But that may not always be the case, according to researchers from The Georgia Institute of Technology has found a way to borrow new medical technology to create painless tattoos.
It is also what gives tattoos their permanence. It does the same for painting Painful. Tattoo artists use needles Release tiny drops of color into the dermis layer beneath the skin, so no matter how many layers of skin peel off over time, the color remains safely trapped under the self-replenishing outer layer.
Pain is a big part of the tattoo experience, but not everyone goes through this process by choice. Tattoos are often used as a medical device as well. For example, cancer patients undergoing repeated radiation treatments are tattooed with tiny reference marks on the machines, which allow the radiation beams to be aimed quickly, accurately and safely every time. Tattoos can be used to remove scars after surgery or to provide a permanent warning of serious medical conditions for some patients.
That group of researchers from The Georgia Institute of Technology is about to develop microneedle technology as an alternative to tattooing. As the name suggests, microneedles are small enough to introduce drugs or medicine into the skin layer without a person actually feeling it. They often collect in large numbers by piercing their skin and are managed using patches that are easily applied to the skin.
The microneedles created by the Georgia Tech team are smaller than grains of sand. Made from real tattoo ink in a “dissolvable matrix” with flexible adhesive. Each microneedle essentially acts like a large image pixel, and when the adhesive is applied, Pressed on the skin, And when left on for minutes, once the ink is removed, the ink melts and stays in the skin, leaving a recognizable image behind, but without the swelling and bleeding associated with traditional tattooing techniques.
The ink used to create each microneedle can be customized to create full-color tattooed images, just like the pixels on your smartphone screen do, and can be used to indicate colors that are only visible under ultraviolet light. Patients as needed Keeping any tattooed medical information confidential.
The study and the corresponding study were Recently presented in a paper It was published in iScience magazine, And it has been found that the tattoos can last for a year, but temporary tattoos have a shorter lifespan than ink.Instead it is recycled. As it stands now, the microneedle system appears to be a good alternative to traditional tattooing methods for marking patients, or even pets.what farmers should do)But it is not yet a complete substitute for painting by a talented artist. Microneedle arrays are relatively small and lack of robustness to produce high-fidelity images. But as the technology slowly improves, the ‘real’ tattooing process may one day be no different. Temporary tattoos used To apply as a child.
