Scientists develop tattoo-like monitoring device

Scientists have developed an ultra-thin, self-adhesive electronics device resembling a temporary tattoo that can record health data about the human heart, brain waves and muscle activity.
Devices that do the same, until now, have been bulky and required conductive fluids or glues.
The device was developed by scientists at the University of Illinois at Urbana-Champaign, Northwestern University, Tufts University, Institute of High Performance Computing in Singapore and Dalian University of Technology in China.
The researchers said in a statement that the device works using a combination of careful theoretical modeling and precise micro-manufacturing.
“Our goal was to develop an electronic technology that could integrate with the skin in a way that is mechanically and physiologically invisible to the user,” John Rogers, a professor in materials science and engineering at University of Illinois, said in a statement. “We found a solution that involves devices we designed to achieve properties that match to the epidermis itself. It’s a technology that blurs the distinction between electronics and biology.”
