Scientists develop ultrathin skin sensors for seamless health tracking - ayx

However, recent research may have found a solution to these problems by introducing ultrathin sensors that cannot be seen by observers or felt by the wearer. In an article recently published in Science Advances, researchers from the Institute of Industrial Science, The University of Tokyo and collaborating institutions reported the development of thin, stretchable on-skin electrodes that are effectively invisible when worn on the face. The new technology can measure biological signals while remaining undetectable by eye and by touch, allowing monitoring to take place under more natural conditions. However, conventional facial electrodes can alter a person's appearance and affect social interactions, creating what are called appearance artifacts – changes in behavior or psychological state caused simply by wearing a device the individual and others can see. "By making wearable electronics that are both fully functional and effectively invisible, we are moving one step closer to a future in which health monitoring and human–machine interaction are seamlessly integrated into everyday life," remarks Matsuhisa.
