Oximeter breakthrough

摘要

Engineers at the University of California, Berkeley, have created a wearable, flexible oximeter that can gauge blood-oxygen saturation in any part of the body.Oximeters use light to detect the ratio of oxygen-rich red blood to darker, less oxygenated blood. Until now, this has only worked on areas of the body that are partially transparent, like the fingertips or earlobes.Using flexible electronics, combined with a new way of measuring oxygenation with reflected light rather than transmitted light, the UC Berkeley team can now measure oxygen levels anywhere in the body. The research could lead to improved wound monitoring and more accurate assessments of transplant patients.
