Noninvasive RFID tag measures your vital signs without body contact

Being able to carry out continuous monitoring of the body’s vital signs could be great for offering early warning about potential abnormalities. But for this kind of technology to ever become mainstream it’s necessary that it can be done in the most noninvasive way possible — meaning no mess of wires and electrodes. That’s something that researchers from Cornell University have been working on with a new project. They have created a new touch-free monitoring system that can keep tabs on a person’s heart rate, blood pressure, and breathing with nothing more invasive than a tiny RFID tag that could be placed on an item of clothing like a shirt pocket.
