Investigation the electrical resistance and thermal behaviour of surface mount device integrated stainless steel electronic yarn

Abstract

The emergence of intelligent textiles in recent years has highlighted the importance of e-textiles (electronic textiles). Electrically conductive textiles can be found in the form of fabrics, yarns, or fibres textile structures. The electronic yarn (E-yarn) was manufacturing by incorporated tinny surface mount electronic device (SMD) into textile conductive yarn. This paper deals with the electrical resistance and thermal properties of SMD LED embedded stainless steel (SS) E-yarn. The relationship between the current voltage curve and total electrical resistance of the electronic yarn was investigated experimentally. In addition, the analytical finding shows that, as the supply voltage increase, the electrical resistance of conductive yarn significantly increased and the surface temperature of both the SS conductive yarn and E-yarn had increased. Furthermore. From the test result, it can be confirmed that, this electronic yarn was suitable to be used for resistive heating elements and use for possible application in wearable e-textiles heating and a new way of energy saving.
