Abstract

The inkjet printing for flexible electronics is an emerging technology that is continuously expanding in different fields, such as healthcare, sports, space science, and, in general, where the traditional rigid electronics is not adequate. In this paper, the design and test of an inkjet-printed device on a flexible substrate are presented. The device is an interdigital capacitor (IDC) fabricated by deposition of conductive ink on a 127 mum-thick polyimide (Kapton) film. First, the electrical characterization of the substrate material is presented. The obtained results are then used for the IDC design. Finally, the prototype is fabricated by means of an inkjet printer and tested in a frequency range from 1 GHz to 5 GHz.
