Additive manufacturing technologies are rapidly transforming the way electronic circuits, sensors, and embedded systems are conceived, fabricated, and tested. Beyond traditional printed electronics, the use of 3D printing (FDM, multi-material deposition, conductive filaments, hybrid structures) enables the fabrication of fully three-dimensional functional devices with customized geometries, integrated wiring, conformal sensors, and mechanically robust architectures. These emerging approaches unlock new opportunities for rapid prototyping, smart objects, wearable systems, industrial monitoring, IoT nodes, and low-cost or disposable instrumentation.

This Special Session aims to gather contributions on materials, processes, design methodologies, characterization techniques, and metrological validation of 3D-printed electronic circuits and sensors.

Topics of interest include, but are not limited to:

• Conductive and functional materials for additive electronics;
• Multi-extrusion FDM systems for electronic manufacturing;
• 3D-printed sensors (mechanical, environmental, chemical, optical);
• Embedded circuitry, antennas, and interconnects;
• Metrology, reliability, and standardization of printed devices;
• Hybrid manufacturing combining additive, subtractive, and PCB technologies;
• Applications in Industry 4.0, IoT, robotics, wearables, and smart structures.

Alfiero Leoni is an Assistant Professor at the University of L'Aquila, Italy, with expertise in digital and mixed-signal integrated system design. His research interests span low-power energy harvesting circuits and systems, analog and mixed-signal sensor front-end and sensor systems, and 3D-printed sensors. He has been actively involved in the development of research activities at the intersection of electronics, Industry 4.0, IoT, and emerging fabrication technologies. His current work focuses on the design, prototyping, and validation of innovative electronic and photonic sensing systems for nuclear physics, industrial, and medical applications.
