Medical applications, nonwoven materials developments

Screen printing is another technique used for realizing a textile electronic cireuit. It is appropriate for realizing electrics and electronics due to its ability to produce patterned, thick layers fiom paste-like materials. Paul et al. (2014) have developed a screen-printed network of electrodes and associated conductive tracks on textiles for medical applications. A polyurethane paste is screen printed onto a woven textile to create a smooth, high surface energy interface layer and a silver paste is subsequently printed on top of this interface layer to provide a conductive track (Fig. 25.19). Merritt et al. (2005) and Karaguzel et al. (2009) have screen-printed conductive stractures on nonwoven textiles They have measured variants of transmission fines and specified their electrical parameters such as DC resistance and line impedance before and after washing.
