electronic tattoo 3d printed onto skin is \'swiss army knife of the future\'
Researchers have found a way to place electronic devices directly on people\'s skin using a 3D printer, paving the way for wearable sensors and even solar cells that can charge electronic devices. Researchers at the University of Minnesota developed 3D Printing technology using ink containing conductive silver sheet, when so- The so-called electronic tattoos are no longer needed. Potential uses of this new technology also include printing biological cells into the wound to help heal the wound, which researchers believe could lead to new medical methods for injuries and skin grafting. \"We are excited about the potential of this new 3D technology -- \"The cost of printing technology using portable printers is less than $400,\" said Professor Michael mcaping, lead author of the study . \". Professor McAlpine envisioned the first use of electronic tattoos in a military environment, helping soldiers on the battlefield by placing sensors that can detect chemical or biological agents. \"We imagine a soldier can take this printer out of his backpack and print directly on the skin the chemical sensors or other electronics they need,\" said Professor McAlpine . \". \"It\'s like the\" Swiss Army knife \"of the future, everything they need is in a portable 3D printing tool. ”The new 3D- Printing technology is part of a growing trend in which scientists have developed electronic tattoos to enhance the natural capabilities of the human body. Researchers at the University of Illinois are currently developing an am \"optoelectronic system\" to monitor the health of the wearer through electronic labeling. Another team at Seoul National University in South Korea has previously developed a flexible skin patch made of graphene that can detect blood sugar levels in people with diabetes. One of the biggest innovations in Professor McAlpine\'s research is the use of computer vision to print tattoos on the skin, even if the tattoo is not completely stationary. \"No matter how hard anyone is trying to keep moving when using a printer on their skin, one person moves slightly and each hand is different,\" says Professor McAlpine . \". \"This printer can track hands . . . . . . And adjust in real time according to the movement and contour of the hand, so the printing of the electronic device keeps its circuit shape. \"The study was published this week in the academic journal Advanced Materials.
