Ultraflexible OLED “skin” can monitor pulse, blood oxygen

Takao Someya  has developed OLED-embedded electronic “skin” for health monitoring applications –particularly pulse monitoring and blood oxygen sensing — at the University of Tokyo. It is thin, and can move with the skin and body, eliminating the need for rigid glass or plastic substrates, and potentially replacing health monitoring devices.

Previous attempts at skin-display tech could only last a few hours, because oxygen and water vapor in the air penetrated the skin, damaging it.  A protective film allows the new “skin” to last for several days. Indium tin oxide electrodes are attached to a very thin substrate, powering ultrathin polymer light-emitting diodes  and organic photodetectors in the skin.
