No one wants to see bloodshed, but blood samples must be collected in medical aid and scientific experiments to tell us relevant information. Recently, the University of Cincinnati and the US Air Force Research Laboratory are developing a skin-detection system similar to a band-aid, which can be converted into various real-time medical data by collecting and analyzing sweat extraction without puncturing the skin.
A team led by Jason Heikenfeld, a professor at the University of Cincinnati, developed a patch containing an integrated circuit, a communication antenna, a master chip, and a microfluidic absorbent paper sweat sampling system that extracts sweat from the skin after it is applied to the surface of the body. And analysis. In order to ensure a long-lasting absorption of sweat, a highly water-absorbent resin gel is used on the patch, and after a few hours of sweat collection, the gel can collect sweat of about 2 to 3 mm.
The patch itself does not have any energy, but like the RFID tags used daily, the relevant signals can be read by the smartphone. Once the phone is close, the patch measures the collected sweat and feeds it back to the phone. And then tell you the problems and symptoms that are currently encountered in the body. The project is currently in the research and development stage.
