For measuring heart rate and oxygen level in the blood, scientists at the University of California has developed flexible oximeter. Everyone knows that the current instruments for measurements tend to be cumbersome, it is not very convenient to use, which cannot be said about the new development. Externally the new oximeter resembles a band-aid. It is thin and elastic. In order to identify appropriate indicators, the oximeter is equipped with red and green OLED elements. Traditional devices use only red and green light.
As seen, the advantage of the new oximeter is not only a convenience. This kind of organic electronics significantly reduces the cost of production of traditional instruments. Undoubtedly, elastic “oximeter-patch” have already been tested and have shown results with the same accuracy, which provide devices obsolete pattern.
