Interdigitated capacitors (IDCs) have become widely used in several fields ranging from gas sensing to microfluidics thanks to their high sensitivity and wide range of applications. Inkjet printing technology has been proposed as a promising method for fabricating such devices, due to its ability to create complex patterns with high accuracy, thus becoming a valid alternative to traditional fabrication methods.

A recently published research article, which is entitled “Inkjet-Printed Interdigitated Capacitors for Sensing Applications: Temperature-Dependent Electrical Characterization at Cryogenic Temperatures down to 20 K”, details the temperature-dependent electrical properties of inkjet-printed IDCs. The study was the result of a collaborative effort between two Italian research groups: the team led by Prof. Nicola Donato (Res4Net member) from the Department of Engineering at the University of Messina, and the group led by Prof. Silva from the Department of Industrial, Electronics and Mechanical Engineering at Roma Tre University.

The core of the research is the electrical characterization of interdigitated structures, usually employed for sensors development, from room temperature down to cryogenic levels. The research performed provides insights that can be useful in future advancement of the design and optimization of inkjet-printed microwave transducers, particularly in the fields of sensing applications.

The study was recently published in the MDPI Instruments journal and was selected as the cover for Volume 7, Issue 3 (September 2023) of the journal . This highlights the relevance of the article and its contribution to ongoing discussions in the scientific community.
