Electronic skin that tracks health status steps closer
Medical News Today

Researchers in Japan have developed an ultra-thin material that attaches to skin and contains electronics that monitor blood oxygen levels.

Writing in the journal Science Advances, scientists from the University of Tokyo describe how they made their prototype “e-skin” from a thin, flexible, organic material that is stable in air.

The e-skin has a protective film comprising five alternating layers of an inorganic material called silicon oxynitrite and an organic material called parylene. This protects the onboard electronics from water vapor and air, extending device lifetimes from the few hours achieved in previous designs to days.

In their paper, the researchers describe incorporating transparent electrodes into the film without damaging it. Once this was achieved, they then created polymer light-emitting diodes (PLEDs) and organic photodetectors using the material.
