Here is an excerpt from an article that speaks to the potential of "health clothes" as a part of our everyday future.  

"There is a conceptual transition from “medical
clothes” for patients to “health clothes” for
citizens. The first category includes medical
clothes that could be relatively cumbersome resulting
from a merge of existing tools and sensors
on regular clothes. This is at present realized
in pre-commercial prototypes such as
Mamagoose, pajamas for the detection of Sudden
Infant Death Syndrome, or in products
such as LifeShirt™, a system providing continuous
ambulatory monitoring of respiratory
and cardiac parameters. In addition to their
health related functionality, these clothes
should be elegant, easy to wear, and include invisible
sensors and information technologies.
This would require medium to long term R&D
for integration of sensors/actuators, energy
sources, processing, and communication functions
within the clothes. Current prototypes
such as SmartShirt™ and “medical assistance
suit” (VTAMN Project) still require further
medical validation. Longer research involving
new fiber materials aims at “e-textiles,” where
sensing, processing, and communications are
integrated in a woven structure to monitor
physiological signals and biomechanical variables.

Very cool!!
