A world of cheap, wearable medical sensors could result from organic electronics

Future fitness trackers could soon add blood-oxygen levels to the list of vital signs measured with new technology developed by engineers at .

UC Berkeley engineers have created a sensor composed of all-organic optoelectronics that uses red and green light. The red and green organic light-emitting diodes (OLED) are detected by the organic photodiode (OPD). The device measures arterial oxygen saturation and heart rate as accurately as conventional, silicon-based pulse oximeters.
