Tiny Technology With a Big Heart

When undergoing medical treatment, physicians frequently determine that a patient's vital signs — such as blood pressure and heart rate — need to be closely monitored. For most patients today, this means a variety of wires and sensors will be attached to their bodies. But thanks to technology developed at NASA, there might be a better way.A new biomedical sensor that incorporates technology pioneered at NASA's Glenn Research Center in Cleveland, Ohio, is currently being developed by a company called Endotronix. The company is investigating using the sensors to measure blood pressure and heart rate.
