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