The term “Smart”
“Smart” can relate to…
The integration of electronics into textiles
Smart Materials (e.g. Phase Change, Shape Memory)
Functional Finishes (e.g. Lotus Effect, no-iron finishing)
Functional Clothing (e.g. Gore-Tex®)
“Smart” = Everything the customer perceives as “smart”
Norms and standards do not exist (maybe coming soon)
Pre-norm: “additional specific and functional properties”, regarding to
optical, electrical, mechanical, chemical or thermal stimulus or reaction
