In recent years, printed electronics reached enormous popularity as a result of their huge potential to offer unique features that are not attainable through traditional fabrication, namely low‐cost production, multifunctionality, stretchability, sustainability, and flexibility. Being expected a galloping increase in the use of printed technologies in the near future, due to the digitalization efforts associated with the Internet of Things and the 4.0 revolution, it is timely and desirable to discuss the joint features, the interrelations, the complementarities, the interdependency, and the most demanding challenges linked to the relation between printed technologies and electronic materials. In this context, this study offers a broad review of the numerous printing technologies used in the processing of electronics, commonly used substrates, the most effective printed electronic materials, and the key post‐printing treatments such as sintering. Disruptive challenges in various printing techniques, (un)expected future research directions of printed electronics, and imminent application trends are also highlighted, following a critical and subjective perspective.

“…To tackle this problem, Song et al 36 presented a unit strengthening approach by increasing the number of struts inside the individual cell, thereby improving the energy threshold for buckling with the overall mass tradeoff. Similarly, Xiao et al 37 elaborately substituted the bending-dominated body-centered cubic (BCC) lattices located in the shearsensitive region with the stretching-dominated octet-truss (OCT) units to search for the balance between weight and performance. In essence, these methods still follow the traditional mass-strength relationship to delay the plastic buckling phenomenon.…”

Biological materials such as conch shells with crossed-lamellar textures hold impressive mechanical properties due to their capability to realize effective crack control and energy dissipation through the structural synergy of interfacial modulus mismatch and lamellar orientation disparity. Integrating this mechanism with mechanical metamaterial design can not only avoid the catastrophic post-yield stress drop found in traditional architectural materials with uniform lattice structures but also effectively maintain the stress level and improve the energy absorption ability. Herein, a novel bioinspired design strategy that combines regional particularity and overall cyclicity is proposed to innovate the connotation of long-range periodicity inside the metamaterial, in which the node constraint gradient and crossed-lamellar struts corresponding to the core features of conch shells are able to guide the deformation sequence with a self-strengthening response during compression. Detailed in situ experiments and finite element analysis confirm that the rotated broad layer stacking can shorten and impede the shear bands, further transforming the deformation of bioinspired metamaterial into a progressive, hierarchical way, highlighted by the cross-layer hysteresis. Even based on a brittle polymeric resin, excellent specific energy absorption capacity [4544 kJ/kg] has been achieved in this architecture, which far exceeds the reported metal-based syntactic foams for two orders of magnitude. These results offer new opportunities for the bioinspired metamaterials to substitute the widespread syntactic foams in specific applications required for both lightweight and energy absorption.

Our previous work reported a novel lattice structure composed of modified face-centered cubic (modified FCC) cells with crossing rods introduced at the center of each cell. In this work, the proposed modified FCC lattice is further investigated to ascertain its compression behaviors under different loading rates. For this purpose, numerical simulations were carried out for compressing the two-dimensional and three-dimensional modified FCC lattice structures with different loading rates, and to compare their deformation modes and energy absorption capacity under different loading rates. In addition, lattice specimens were fabricated using selective laser melting technology and quasi-static compression experiments were performed to validate the finite element simulations. The results indicate that the proposed modified FCC lattices exhibit better load-bearing capacity and energy absorption than the traditional FCC lattices under different loading rates. Under high-speed loading, the modified FCC structure is less susceptible to buckling, and the length ratio of the central cross-rod corresponding to maximum energy absorption capacity is larger.
