Organic Blood Oxygen Sensor Offers More Flexibility

Dec-14-14 An organic blood sensor that can be applied to the skin like a bandage provides a more flexible and less expensive alternative to conventional monitors.

While traditional monitors work by beaming infrared and red light through the skin in order to measure the oxygen level, the sensor from the group at UC Berkeley uses red and green light instead. The red and green organic LEDs, along with translucent light detectors, were deposited on a piece of flexible plastic, which can then be placed on the skin to monitor blood flow.

In tests, the organic device's efficiency proved comparable to that of conventional monitors.
