”Smart clothes” are clothes that employ new technologies: technological developments have made it possible to integrate electronic components into conventional garments. In demanding conditions, such as working in heavy industries, very specific demands are placed on work apparel and materials, as they must protect the wearer from any hazards found in the working environment. Smart clothes design offers new material technology applications to make work apparel safer and more specifically suited to the work and environment in question. Smart clothes also make it possible for the wearer’s vital functions to be monitored, using, for example, an electromyograph (EMG).
