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”

� Exact definition has not been found yet

� Norms and standards do not exist

Smart Textiles – An Introduction

� „Intelligent Textiles“: Enhanced functionality

� Integration of electronic elements / circuits (e-textiles)

� Realisation of sensors, actors, conductors
