Special Issue Information

Dear Colleagues,

Flexible and printable electronics technologies in additive manufacturing have offered a new way of synthesizing printable materials and devices for fabrication purposes. The Special Issue will showcase cutting-edge research studies that refine a scientific understanding relevant for printable and flexible electronics while striving towards low-cost ecofriendly materials and devices that can potentially transform the field of microelectronics by disrupting the entire chain, from design to manufacturing to application.

Among the different additive manufacturing technologies, those based on flexible electronics technologies represent a strong and intensive research effort in both industry and academia, leading to the publication of many scientific papers over the last few years. This huge interest has resulted in this Special Issue which offers researchers in this area the opportunity to publish their research work through research papers or review papers.

The topics of interest covered by this Special Issue include, but are not limited to, the following:

  • Printing fabrication and methods;
  • Curing and sintering processing techniques;
  • Advanced manufacturing technologies;
  • Flexible hybrid electronics (FHE);
  • The assembly or packaging of conventional electronics on flexible substrates;
  • The heterogenous integration of printed elements onto conventional electronics;
  • Sensors and devices, and their related properties;
  • Disposable and sustainable materials and substrates;
  • Stretchable and flexible materials and devices;
  • The characterization and testing of printable materials and devices;
  • The design and simulation of printable materials and devices;
  • End-user applications, such as OLED, OPV and solar cells, RFID and antennas, touch surfaces, wearable and smart textiles, smart patches, health monitoring and biosensors, anti-counterfeit solutions, temperature and pressure sensors, thermoelectric and energy storage/harvesting, sensors, smart packaging, EV batteries, and many others.

In this study, Silicon Carbide (SiC) nanoparticle-based serigraphic printing inks were formulated to fabricate highly sensitive and wide temperature range printed thermistors. Inter-digitated electrodes (IDEs) were screen printed onto Kapton® substrate using commercially avaiable silver ink. Thermistor inks with different weight ratios of SiC nanoparticles were printed atop the IDE structures to form fully printed thermistors. The thermistors were tested over a wide temperature range form 25 °C to 170 °C, exhibiting excellent repeatability and stability over 15 h of continuous operation. Optimal device performance was achieved with 30 wt.% SiC-polyimide ink. We report highly sensitive devices with a TCR of −0.556%/°C, a thermal coefficient of 502 K (β-index) and an activation energy of 0.08 eV. Further, the thermistor demonstrates an accuracy of ±1.35 °C, which is well within the range offered by commercially available high sensitivity thermistors. SiC thermistors exhibit a small 6.5% drift due to changes in relative humidity between 10 and 90%RH and a 4.2% drift in baseline resistance after 100 cycles of aggressive bend testing at a 40° angle. The use of commercially available low-cost materials, simplicity of design and fabrication techniques coupled with the chemical inertness of the Kapton® substrate and SiC nanoparticles paves the way to use all-printed SiC thermistors towards a wide range of applications where temperature monitoring is vital for optimal system performance.
