The present study shows fabrication of electronic resistor by means of inexpensive inkjet printing method on the photonic paper substrate at room temperature. The objective of this work is to demonstrate the feasibility of inkjet printed resistor with a different resistance values for the application of electronic devices. Inkjet printing process is performed using magnetostrictive inkjet printhead designed by our laboratory which use a magnetostrictive material, Terfenol-D rod as an actuation mechanism in Fig. 1 . For printing resistor component on photonic paper substrate, we use two functional inks: one is the silver nanoparticle ink which is used to make conducting layer, the other one is poly (3,4-ethylene dioxythiophene): poly (styrene sulfonate) (PEDOT:PSS) inks that is used to make resistive layers in Fig. 2. The resistivity of printed resistor is altered with different resistance values with respect to the printing layers and length of the resistor line. An electronic circuit is sketched and tested using fabricated resistor component. The printed resistor with various resistance values provides an important building block for low cost, printed electronic circuit application. From theses results, we can show that magnetostrictive inkjet printhead has a potential to fabricate electronic devices.
