organic oximeter

A disposable organic oximeter
December 12, 2014

UC Berkeley engineers have created a pulse oximeter 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. (Credit: Yasser Khan) Engineers at UC Berkeley have designed a wearable organic (carbon-based) oximeter (for  blood-oxygen levels) device that could ultimately be thin, cheap, and flexible enough to be slapped on like a Band-Aid. “There are various pulse oximeters already on the market that measure pulse rate and blood-oxygen saturation levels, but those devices use rigid conventional electronics, … more…
