Fabrication of IDT electrode onto cellulose Electro-Active Paper by inkjet printing

초록

This paper investigates a direct inkjet printing method for electrode patterning on cellulose Electro-Active Paper (EAPap). Flexibility and transparency of the EAPap are advantageous for a versatile substrate in flexible printable electronics. The effects of curing conditions are evaluated by electrical resistivity and morphological analysis. To fabricate EAPap device, inter-digital transducer (IDT) electrodes are printed on the EAPap with drop-on-demand inkjet printing method. Silver patterns are obtained from organometallic silver ink by jetting and heat treatment at 160°C in air. IDT patterns are made on cellulose for variety and extensive application of inkjet printing electronics. © 2012 SPIE.
