Assembly and applications of 3D conformal electronics on curvilinear surfaces

“…Recently, although it is still in the initial phase, additive technology is also exploring the possibility of making electronic and electromagnetic devices, thanks to the emergence of promising new materials, along with the possibility of implementing complex structures and geometries. For example, in electronics, 3D printers are being used for the manufacture of printed sensors, conformal electronics, and stretchable electronics [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. For microwave devices, additive technology is primarily focused on the design of 3D structures, such as waveguide devices, antennas, and sensors [ 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”

This work presents a study on the implementation and manufacturing of low-cost microwave electronic circuits, made with additive manufacturing techniques using fused deposition modeling (FDM) technology. First, the manufacturing process of substrates with different filaments, using various options offered by additive techniques in the manufacture of 3D printing parts, is described. The implemented substrates are structurally analyzed by ultrasound techniques to verify the correct metallization and fabrication of the substrate, and the characterization of the electrical properties in the microwave frequency range of each filament is performed. Finally, standard and novel microwave filters in microstrip and stripline technology are implemented, making use of the possibilities offered by additive techniques in the manufacturing process. The designed devices were manufactured and measured with good results, which demonstrates the possibility of using low-cost 3D printers in the design process of planar microwave circuits.

“…Such progress of NFES has been based on 2D planar surfaces, thereby fabrication of nanofiber patterns/structures has been limited to 2D surfaces. [ 7,8,10,16 ] However, the fabrication of functional nanofiber on 3D surfaces is essential not only to obtain compatibility with 3D living organisms and conformal electronics [ 17 ] but also to provide new functionalities that only arise on multidimensional surfaces. [ 18,19 ]…”

This paper reports a high‐resolution, template‐free, and direct‐printing method of functional nanofiber on 3D surfaces using a self‐aligning nanojet (SA‐N) in near‐field electrospinning (NFES). In the lowest regime of NFES, the cone‐jet transition is induced by the surface current, which leads to a unique jetting configuration where the microscale Taylor cone (microcone) is formed on the surface of the spherical‐shape droplet. The microcone rapidly develops to the nanoscale jet where the tangential electric force dominates the kinematics of the charged jet. The spherical‐shape ejection boundary allows the jetting angle from 0° to ±90° in both convex and concave surfaces, enabling precise deposition of nanofiber regardless of the curvature of the 3D surfaces. Using SA‐N, precise printing of functional nanofiber is successfully demonstrated on various 3D geometries, including convex, concave, and inner surface of the 3D structure. The direct‐printing ability of nanofiber on 3D surfaces using SA‐N will be a promising strategy to utilize various functional polymers in flexible electronics, printed electronics, optics, and biomedical engineering.
