Wearable, Wireless Blood Oxygen Sensor

Pulse oximetry’s history dates to 1860, proceeds to Karl Matthes’ ear oximeter in 1936, and comes to the chief of surgery at Henry Ford Hospital in 1939 who wanted to guard against anoxia during surgical anesthesia. Oximeters are now ubiquitous in hospitals, but not easily transportable for everyday activities of people who suffer from, say, serious asthma or COPD. Electrical engineers at UCal-Berkeley, however, are developing a disposable oximeter that’s worn like a Band-Aid and relies on red and green “organic” LED lights (OLEDs) to detect a ratio of high and low oxygen levels.
