“…Finally an image masking algorithm, similar to Koskinen et al [12] used, was introduced to further optimize the printing process and to enable printing 'stacked-coin' structure with only one image file. This masking algorithm produced ink coverage equivalent to approx.…”

“…Inkjet-printed conductors are typically thinner than conventional copper foils and have a somewhat porous structure, which have been shown to significantly improve performance in bending tests [10]. In addition, flexible circuit board manufactured with inkjet technology has been shown to be capable of replacing an existing flexible circuit board manufactured with conventional methods for example in a mobile phone [11,12]. Therefore inkjet printing is a feasible alternative for manufacturing flexible electronics.…”

Stretchable circuits have the potential to enable integrating electronics in everyday objects, but also skin-like, imperceptible electronic applications. However, manufacturing stretchable electronics requires developing novel manufacturing methods and using novel materials at least as substrate. Since the elastic materials for stretchable electronics are relatively soft, using traditional manufacturing methods becomes more problematic, whereas contactless material deposition by inkjet-printing is unaffected by such material properties. This study concentrates on feasibility analysis of using inkjet printing in manufacturing of stretchable electronics. First, printing related challenges are evaluated by manufacturing test structures with inkjet-printer using silver nanoparticle ink on elastic thermoplastic polyurethane substrate and sintering structures in convection oven. Adhesion between ink and substrate, but also sheet resistance, is evaluated. A minimum sheet resistance approx. of 26 m was obtained, and peak strains of inkjet-printed conductors are found to be between 1.0 % and 1.5 %, but conductivity is observed to be almost fully reversible when strain is released.

Abstract-This paper describes the computer-aided-design (CAD)-assited microwave characterization of coplanar waveguide (CPW) lines formed by ink-jet printed technology on flexible polyethylene terephthalate (PET) substrates. A spacemapping technique is used to link the measured results with simulations and the mapping is used to extract the electrical properties of the ink and supporting dielectric spacer employed during measurements. Results indicate that the losses in lines are predominantly due to the loss tangent of the substrate and the conductivity of the ink. Estimates of the conductivity of the ink and the dielectric constant of the spacer used during measurement were obtained as 2.97 × 10 7 2.97 × 10 7 2.97 × 10 7 S/m, and 1.79 respectively.

“…It has been shown that electronics can be realized on paper substrates through simple processes such as inkjet printing. This could result in further cost savings through roll-to-roll mass manufacturing options [3]. Paper is light weight, environmentally friendly (biodegradable) and comes from a renewable source, making it a very attractive option for such designs.…”
