Researchers from UC Berkeley developed a pulse oximeter sensor that is made entirely from organic optoelectronics. The flexible oximeter can measure arterial oxygen saturation and heart rate, and performs as well as silicon-based pulse oximeters.

The sensor is made from red and green flexible OLED lighting devices and an organic photodiode (OPD). Unlike regular devices, this new organic sensor device is thin, flexible and (theoretically) cheap.
