NIST Sensor Detects Heartbeat

Facebook X LinkedIn Email
GAITHERSBURG, Md., Oct. 28, 2010 — Researchers from the National Institute of Standards and Technology (NIST) and the German national metrology institute have used NIST’s miniature atom-based magnetic sensor to successfully track a human heartbeat, confirming the device’s potential for biomedical applications. The study of the NIST mini-sensors is the first to be performed under conditions resembling a clinical setting, whereas before they were operated mostly in physics laboratories. The new experiments were carried out at the Physikalisch Technische Bundesanstalt (PTB) in Berlin, in a building described as...Read full article
