Fabrication of hight conductive circuits via inkjet printting

A convenient method has been developed for applying patterned nickel tracks on polyester fabric for electronic applications. The process comprises inkjet printing of an aqueous palladium (II) solution on surface treated polyester fabric, followed by reduction to metallic palladium and electroless nickel plating. The nano-structure of the nickel pattern was investigated using scanning electron microscopy (SEM) and the size of the nanoparticles were in a rang of 20-100nm.In addition the electrical conductivity was evaluated using four probe technique and results showed reliable and stable conductivity about 2632S/m. Using a desktop inkjet printer,the procedure was successfully applied for manufacturing inter digitated conductive pattern as used for many applications such as antenna, electronic circuit, coil, ECG sensor, and capacitor .
