Special Issue Information

Dear Colleagues,

Printed electronics have been attracting much interest as a disruptive technology for electronic devices. For environmental sustainability, they are promising because of the potential for subtractless fabrication compared to photolithography or chemical processes. In addition, flexible sensors can be implemented for smart healthcare, the IoT (Internet of Things), or green technologies at low cost and with mass production based on printed electronics. 

This Special Issue focuses on the latest developments in and applications of printed electronics. It will accept recent studies of fabrication processes: pretreatment, printing (gravure, inkjet, etc.), post-printing (drying, sintering, lamination, packaging, etc.), etc. It will also welcome applications for medicine (motion detection and biosignal measurement), environmental detection (humidity and temperature), wireless detection (RFID and power transmission), electrical functions (display and memory), photovoltaics, and others based on printed electronics.

We hope that this Special Issue will be a beneficial and productive medium for researchers devoted to developing printed electronics.

Dr. Hyunkyoo Kang

This paper presents the first successful implementation of fully printed electronics for flexible and wearable smart multi-pad stimulation electrodes intended for use in medical, sports and lifestyle applications. The smart multi-pad electrodes with the electronic circuits based on organic electrochemical transistor (OECT)-based electronic circuits comprising the 3–8 decoder for active pad selection and high current throughput transistors for switching were produced by multi-layer screen printing. Devices with different architectures of switching transistors were tested in relevant conditions for electrical stimulation applications. An automated testbed with a configurable stimulation source and an adjustable human model equivalent circuit was developed for this purpose. Three of the proposed architectures successfully routed electrical currents of up to 15 mA at an output voltage of 30 V, while one was reliably performing even at 40 V. The presented results demonstrate feasibility of the concept in a range of conditions relevant to several applications of electrical stimulation. Full article

Inkjet-printed strain gauges on flexible substrates have recently been investigated for biomedical motion detection as well as the monitoring of structural deformation. This study performed a topographical analysis of an inkjet-printed strain gauge constructed using silver conductive ink on a PET (polyethylene terephthalate) substrate. Serpentine strain-gauge sensors of various thicknesses and widths were fabricated using inkjet printing and oven sintering. The fabricated gauge sensors were attached to curved surfaces, and gauge factors ranging from 2.047 to 3.098 were recorded. We found that the cross-sectional area of the printed strain gauge was proportional to the gauge factor. The correlation was mathematically modelled as y = 0.4167ln(x) + 1.3837, for which the coefficient of determination (R2) was 0.8383. Full article
