Special Issue Information

Dear Colleagues,

Printed, organic, and/or flexible electronics commonly known as printed electronics aim to complement the manufacture of conventional electronics (either silicon or PCB) with new printing concepts and contribute to the next electronic revolution. The related manufacturing processes are generally of low material waste and low energy consumption. They take advantage of all the characteristics of solvent-based materials to prepare stacks of structured electrical layers in a much simpler and cost-effective way. The development of devices and circuits based on these processes opens the door to disposable, flexible, and low-cost systems.

We are launching a Special Issue of the journal Applied Sciences entitled “Printed Electronics Processing”. This issue will cover the various experimental and theoretical aspects related to printed electronics processing and its applications. This Special Issue will publish innovative research articles related to flexible electronic materials, printing techniques, additive manufacturing, and components or systems that meet any of the above criteria.

This Special Issue aims to encourage and publish research on the challenges and opportunities associated with developing high-throughput, low-cost manufacturing methods for electronic applications. The topics listed below indicate the range of work that is relevant to the issue:

  • Printable materials for the implementation of conductors, semiconductors, dielectrics, and sensors;
  • New printing processes and technologies;
  • Large-area and/or high-volume deposition and patterning techniques;
  • Process variability, reliability, and yield;
  • Devices and systems facing new applications.

In this paper, an organic, fully recyclable and eco-friendly 20-bit inkjet-printed chipless RFID tag is presented. The tag operates in the near field and is implemented by means of chains of resonant elements. The characterization and manufacturing process of the tag, printed with a few layers of a commercial organic ink on conventional paper substrate (DIN A4), are presented, and tag functionality is demonstrated by reading it by means of a custom-designed reader. The tags are read by proximity (through the near field), by displacing them over a resonator-loaded transmission line, and each resonant element (bit) of the tag is interrogated by a harmonic signal tuned to the resonance frequency. The coupling between the reader line and the resonant elements of the tag produce and amplitude modulated (AM) signal containing the identification (ID) code of the tag. Full article

Activated carbon (AC) and multiwalled carbon nanotubes (MWCNTs) have been extensively investigated in recent decades as electrical double-layer capacitor (EDLC) electrode materials for supercapacitors, owing to their superior capacitive properties and cycling stability performance. However, in the modern electronics industry, ternary electrode materials have been designed to develop high-performance and efficient energy storage devices. EDLC-based ternary materials are of great importance, where all the present components participate both individually and as a multicomponent electrode system to promote high-electrochemical performance electrode materials. In this study, we have incorporated an optimized content of boron nitride nanotube (BNNT) powder into a binary material composed of AC and MWCNTs to enhance their electrochemical performance using a pneumatic printer. The printed MWCNTs/AC/BNNTs ternary composite electrode material has shown a maximum specific capacitance of 262 F g−1 at a minimum current density of 1 A g−1, with a capacitance retention of 49.61% at a maximum current density of 10 A g−1. These results demonstrate that the printable MWCNTs/AC/BNNTs ternary composite electrode material is a potential candidate for the development of high-performance supercapacitors. Full article

The development of electronic devices with enhanced properties of transparency and conformability is of high interest for the development of novel applications in the field of bioelectronics and biomedical sensing. Here, a fabrication process for all organic Organic Field-Effect Transistors (OFETs) by means of large-area, cost-effective techniques such as inkjet printing and chemical vapor deposition is reported. The fabricated device can operate at low voltages (as high as 4 V) with ideal electronic characteristics, including low threshold voltage, relatively high mobility and low subthreshold voltages. The employment of organic materials such as Parylene C, PEDOT:PSS and 6,13-Bis(triisopropylsilylethynyl)pentacene (TIPS pentacene) helps to obtain highly transparent transistors, with a relative transmittance exceeding 80%. Interestingly enough, the proposed process can be reliably employed for OFET fabrication over different kind of substrates, ranging from transparent, flexible but relatively thick polyethylene terephthalate (PET) substrates to transparent, 700-nm-thick, compliant Parylene C films. OFETs fabricated on such sub-micrometrical substrates maintain their functionality after being transferred onto complex surfaces, such as human skin and wearable items. To this aim, the electrical and electromechanical stability of proposed devices will be discussed. Full article
