Flexible sensor measures blood-oxygen anywhere in the body - short science news

A new type of sensor (oximeter) allows detection of the blood-oxygen levels over large areas of the body, providing crucial medical information.

The sensor is made of organic electronics printed on flexible plastic that molds to the shape of the body. It can detect blood-oxygen levels at nine points in a grid and can be placed anywhere on the skin. Previous oximeters only work on “transparent” areas of the body, such as fingertips, but the new design can be used anywhere.

The device has many applications: map oxygenation of sky grafts, monitor transplanted organs and supervise healing wounds.
