“…As the printability of the complete battery in one single print (or "one-shot") via VPP still remains one of the main targets to achieve, it is important to note that having composite resins with the same polymeric matrix would improve the adherence between the various layers and components (electrodes, current collectors, electrolyte) in the green state. While multimaterial printing options [42][43][44] had been widely commercialized for material extrusion [2,45], or inkjet additive manufacturing processes, their counterparts for VPP are still scarce as only few attempts at the laboratory scale have been carried out over the last years. These attempts have generally resulted in an exponential decrease in the production rate.…”

“…A hollow CAD model of an isotropic cubic + octet plate-lattice with ρ cubic+octet = 0.3 (shown in Fig. 7) was printed in CFRP via the projection micro-stereolithography (PμSL) system developed in the previous studies [37,50]. After printing, the…”

Plate-based lattices are predicted to reach theoretical Hashin-Shtrikman and Suquet upper bounds on stiffness and strength. However, simultaneously attaining high energy absorption in these plate-lattices still remains elusive, which is critical for many structural applications such as shock wave absorber and protective devices. In this work, we present bi-material isotropic cubic + octet sandwich plate-lattices composed of carbon fiber-reinforced polymer (stiff) skins and elastomeric (soft) core. This bi-material configuration enhances their energy absorption capability while retaining stretching-dominated behavior. We investigate their mechanical properties through an analytical model and finite element simulations. Our results show that they achieve enhanced energy absorption approximately 2-2.8 times higher than their homogeneous counterparts while marginally compromising their stiffness and strength. When compared to previously reported materials, these materials achieve superior strengthenergy absorption characteristics, making them an excellent candidate for stiff and strong, lightweight energy absorbing applications.

“…As a result, after triggered by instantaneous stimuli, motile plant structures exhibit fast mechanical movements in a few seconds or less 9 . By mimicking dynamic architectures in nature, a shape-morphing system 10 , 11 incorporated with smart materials has emerged to create on-demand 3D microstructures 12 , 13 , e.g., microrobots 14 , 15 , metamaterials 16 , 17 , 4D printing technology 18 , 19 and reconfigurable electronics 20 , 21 . However, like tropistic motion, all of the shape movements in these systems developed so far rely exclusively on external stimuli, and result in a slow response compared to the nastic model.…”

Motile plant structures such as Mimosa pudica leaves, Impatiens glandulifera seedpods, and Dionaea muscipula leaves exhibit fast nastic movements in a few seconds or less. This motion is stimuli-independent mechanical movement following theorema egregium rules. Artificial analogs of tropistic motion in plants are exemplified by shape-morphing systems, which are characterized by high functional robustness and resilience for creating 3D structures. However, all shape-morphing systems developed so far rely exclusively on continuous external stimuli and result in slow response. Here, we report a Gaussian-preserved shape-morphing system to realize ultrafast shape morphing and non-volatile reconfiguration. Relying on the Gaussian-preserved rules, the transformation can be triggered by mechanical or thermal stimuli within a microsecond. Moreover, as localized energy minima are encountered during shape morphing, non-volatile configuration is preserved by geometrically enhanced rigidity. Using this system, we demonstrate a suite of electronic devices that are reconfigurable, and therefore, expand functional diversification.
