GE researchers develop disposable, wireless vital sign monitor patch

The innovation in wireless vital sign monitoring is coming fast and furious. The latest to reveal its approach is GE, which has developed a wrist-worn patch about the size of a Band-Aid that can be used to remotely analyse sweat and check vital signs. It's expected to be used after a patient is no longer being treated and has returned home. The device adheres to the inside of the wrist.

The technology is based upon research that had long been shelved at GE on organic light-emitting diodes (OLEDs). Researchers resurrected the work on OLEDs as the basis of this sensor technology; it enables a small, flexible patch with the computing power of an inflexible silicon-based chip. The monitors are already in clinical trials to track hydration levels during intense exercise; the testing could also be expanded to a measure of stress.
