In an effort to bring health monitoring to the patient, scientists from the University of Arkansas have developed a micro-sensor that monitors vital signs and can be incorporated into smart fabrics for wearable illness prevention. With this “point-of-care” testing, physicists Soyoun Jung, Taeksoo Ji and Vijay Varadan are making it possible for the continuous monitoring of signs including respiration, heart rate, ECG, and body temperature outside the doctor’s office.
