Special Issue Information

Dear Colleagues,

Three-dimensional object printing technologies, i.e., 3D-printing, or additive manufacturing in general, are an invention of the last century, but have seen increasing interest and use especially in recent research and industrial applications. Reasons are their versatility, ease-of-use and cost effectiveness compared to standard processes. They are by now ideally suited for rapid-prototyping and small series production. Fields which are of special importance in a modern world, which constantly seeks improvement, the more through individualized designs. 3D-printing enables the development and ultra-fast fabrication of individualized, light-weight, optimized components for a variety of application areas such as: aerospace, automobile, mobile devices, industrial components, robotics and medicine.

Layer-printing technologies, such as inkjet-, aerosol jet, or electrohydrodynamic (EHD) printing, are sometimes also referred to as 2.5D-printing, since, more often, they are used to fabricate functional layers on various types of substrates. While the functional layers may be conductive or made of dedicate functional materials to achieve advanced sensory properties, the substrates can be conformable polymers (especially PDMS and derivates), but also foils, papers or 3D-printed parts of complex shapes. Less often, but the more a topic of vivid research, inkjet-printing has been used to fabricate also all integrated (e.g. including front-end, wiring, read-out circuitry, signal processing and transmission), often conformable, sensor systems.

The goal of this Special Issue is to invite high-quality, state-of-the-art research papers that deal with challenging issues, novel applications and methods for printed sensors and sensor system. We solicit original papers of unpublished and completed research that are not currently under review by any other conference/magazine/journal. Topics of interest include, but are not limited to, the following:

  • Novel 3D- and inkjet-printed sensor designs and system concepts
  • Emerging materials, methods and technologies for printed sensors and systems
  • Simulation and modelling of printed sensors and systems
  • Hybrid printed systems and systems on foil and flexible substrates
  • Recent and future applications of printed sensors in industry and research
  • Soft matter sensor systems and applications

With the growing significance of printed sensors on the electronics market, new demands on quality and reproducibility have arisen. While most printing processes on standard substrates (e.g., Polyethylene terephthalate (PET)) are well-defined, the printing on substrates with rather porous, fibrous and rough surfaces (e.g., uncoated paper) contains new challenges. Especially in the case of inkjet-printing and other deposition techniques that require low-viscous nanoparticle inks the solvents and deposition materials might be absorbed, inhibiting the formation of homogeneous conductive layers. As part of this work, the sheet resistance of sintered inkjet-printed conductive silver (Ag-) nanoparticle cross structures on two different, commercially available, uncoated paper substrates using Van-der-Pauw’s method is evaluated. The results are compared to the conductivity of well-studied, white heat stabilised and treated PET foil. While the sheet resistance on PET substrate is highly reproducible and the variations are solely process-dependent, the sheet resistance on uncoated paper depends more on the substrate properties themselves. The results indicate that the achievable conductivity as well as the reproducibility decrease with increasing substrate porosity and fibrousness. Full article
