Another "smart shirt" was presented yesterday at the World Congress of Cardiology, in Barcelona.

A "smart" shirt, incorporating stainless steel threads, has been
developed by European scientists to monitor heart patients on the move.

The shirt is capable of recording an electrocardiogram—a test of
electrical activity of the heart—which is then transmitted over the
mobile phone network to a central monitoring center, researchers told
the World Congress of Cardiology on Monday.

The target market for this prototype is remote patient monitoring at home. A key problem with ECG monitoring is the need to properly place and attach electrodes to patients. If researchers can replace electrodes with a snug fitting undershirt, the problems of placement and the biocompatibility and patient tolerance of adhesives go away.
