Special Issue Information

Dear Colleagues,

Nanomaterials for flexible and printed electronics endow electronic devices with novel flexibility, foldability, high efficiency, and scalability, overcoming the restrictions of silicon-based electronics and greatly expanding the range of applications in various fields, e.g., in flexible displays, electronic textiles, energy storage devices, sensory skins, etc. Consequently, flexible and printed electronics have attracted widespread attention from both academic and industrial communities, and have witnessed remarkable breakthroughs in terms of material development, device fabrication, packaging, and integration.

The aim of this Special Issue entitled “Nanomaterials for Flexible and Printed Electronics” is to provide a forum for researchers and practitioners to present and review the latest advances regarding the development, challenges, and future perspectives of multiscale manufacturing toward nanomaterials for flexible and printed electronics, with new materials, processes, printing technologies, and applications. Topics of interest include, but are not limited to, the following:

  1. Nanomaterials synthesis, characterization, modeling, and applications, along with nanodevice fabrication and testing;
  2. Organic light-emitting diodes, organic nanotransistors, memory nanodevices, energy storage nanodevices, sensors, and functional nanodevices, conductive electrodes, or circuits;
  3. Novel applications, including in displays, large-area sensors, functional nanodevices, RFID tags, smart sensors, nanofabrics, and paper-based devices;
  4. Novel, large-area processing methods, such as inkjet printing, spray pyrolysis, screen printing, solution deposition, and roll-to-roll processing.

This paper reports a high-performance humidity sensor made using a novel cellulose nanofiber (CNF)–silver nanoparticle (AgNP) sensing material. The interdigital electrode pattern was printed via reverse-offset printing using Ag nano-ink, and the sensing layer on the printed interdigitated electrode (IDE) was formed by depositing the CNF-AgNP composite via inkjet printing. The structure and morphology of the CNF-AgNP layer are characterized using ultraviolet–visible spectroscopy, an X-ray diffractometer, field emission scanning electron microscopy, energy-dispersive X-ray analysis, and transmission electron microscopy. The humidity-sensing performance of the prepared sensors is evaluated by measuring the impedance changes under the relative humidity variation between 10 and 90% relative humidity. The CNF-AgNP sensor exhibited very sensitive and fast humidity-sensing responses compared to the CNF sensor. The electrode distance effect and the response and recovery times are investigated. The enhanced humidity-sensing performance is reflected in the increased conductivity of the Ag nanoparticles and the adsorption of free water molecules associated with the porous characteristics of the CNF layer. The CNF-AgNP composite enables the development of highly sensitive, fast-responding, reproducible, flexible, and inexpensive humidity sensors. Full article

Traditional printed electronics processes have recently been utilized within 3D-printed structures where components and interconnects are introduced during manufacturing disruptions. The dielectric performance of 3D-printed materials has a low-resolution problem, and many technologies have been proposed for direct printing on a 3D curved surface or structure. This paper reports a humidity sensor fabricated with a 3D-printed electrode and cellulose nanofibers on a curved surface. The electrode part of an interdigital electrode (IDE) sensor is printed on a flat glass substrate and a 3D-curved glass substrate using a double blanket reverse offset. Subsequently, a cellulose nanofiber emulsion is coated onto the IDE pattern as a sensing layer with a dispenser. The electrical impedance of the sensor is measured with the relative humidity (RH) changes between 10% and 90% RH. The sensor demonstrates a high repeatability and sensitivity, even on a 3D curved substrate. This technology provides a promising method to integrate humidity sensors and 3D deformable surfaces.
