Antennaless RFID tags solve problem of tracking metal and liquids

February 3, 2012 2:33 am | News | Comments

Most RFID tags that are to be used on metal objects are made by placing an antenna on a spacer. Such tags can be easily damaged because they stick out. New tags, developed by North Dakota State University researchers and being presented at an upcoming IEEE workshop, use the metal objects themselves as the antenna.

First-of-its-kind head patch monitors brain blood flow and oxygen

February 1, 2012 11:09 am | News | Comments

A research team led by investigators at Mayo Clinic in Florida has found that a small device worn on a patient's brow can be useful in monitoring blood oxygen in stroke patients in the hospital. Unlike a pulse oximeter, which also performs this task, the head patch uses near-infrared spectroscopy to quickly the presence of another stroke.
