“…After peeling off the cross-linked PHEMA hydrogel film, a heterogeneous crease morphology is generated on the surface of PDMS. We attribute it to the osmotic stresses that induced a surface-wrinkling instability during the swelling of the confined domain, which has been observed in previous surface-modified strategies. − Then, we find that the widths and depths of the ridges can be adjusted by changing the concentration of HEMA (Figure a–c). To present the ridges more clearly, we remodel the 3D topography using FEA (Figure d–f) and analyze their vertical and lateral sizes (Figure g,h).…”

Contact lens sensors provide a noninvasive approach for intraocular pressure (IOP) monitoring in patients with glaucoma. Accurate measurement of this imperceptible pressure variation requires highly sensitive sensors in the absence of simultaneously amplifying IOP signal and blinking-induced noise. However, current noise-reduction methods rely on external filter circuits, which thicken contact lenses and reduce signal quality. Here, we introduce a contact lens strain sensor with an anti-jamming ability by utilizing a self-lubricating layer to reduce the coefficient of friction (COF) to remove the interference from the tangential force. The sensor achieves exceptionally high sensitivity due to the strain concentration layout and the confined occurrence of sympatric microcracks. The animal tests prove our lens can accurately detect IOP safely and reliably.

“…As one promising direction of interdisciplinary fields, the study of bioinspired structural materials is booming. [ 1,2,12,13,158–163 ] Various bioinspired materials, partially including bioinspired nacre‐like materials, [ 69,76,77,83 ] bioinspired inverse nacre‐like materials, [ 74,164,165 ] bioinspired multiple‐arch elastic structural materials, [ 166,167 ] bioinspired polymeric honeycomb woods, [ 168,169 ] cuttlebone‐inspired cellular materials, [ 170–173 ] as well as bioinspired Bouligand structural materials [ 151–153,174 ] have been fabricated. Many works showed that bioinspired materials with 3D bulk forms would occupy an increasingly prominent position in widespread structural applications.…”

Biological materials, although composed of meager minerals and biopolymers, often exhibit amazing mechanical properties far beyond their components due to hierarchically ordered structures. Understanding their structure‐properties relationships and replicating them into artificial materials would boost the development of bulk structural nanocomposites. Layered microstructure widely exists in biological materials, serving as the fundamental structure in nanosheet‐based nacres and nanofiber‐based Bouligand tissues, and implying superior mechanical properties. High‐efficient and scalable fabrication of bioinspired bulk structural nanocomposites with precise layered microstructure is therefore important yet remains difficult. Here, we focus on one straightforward bottom‐up film‐to‐bulk assembly strategy for fabricating bioinspired layered bulk structural nanocomposites. The bottom‐up assembly strategy inherently offers a methodology for precise construction of bioinspired layered microstructure in bulk form, availability for fabrication of bioinspired bulk structural nanocomposites with large sizes and complex shapes, possibility for design of multiscale interfaces, feasibility for manipulation of diverse heterogeneities. Not limited to discussing what has been achieved by using the current bottom‐up film‐to‐bulk assembly strategy, we also envision how to promote such an assembly strategy to better benefit the development of bioinspired bulk structural nanocomposites. Compared to other assembly strategies, the highlighted strategy provides great opportunities for creating bioinspired bulk structural nanocomposites on demand.This article is protected by copyright.

“…There are many network architectures in nature, and common ones include bones, glass sponges, porcupine quills, etc. [ 203–208 ] Bone is composed of network trabeculae and bone marrow, and the distributions of trabeculae and bone marrow are used to meet the maximum load and density of the bone. Therefore, microstructures with high mechanical strength for bone can provide inspiration for the preparation of bionic scaffolds and composites.…”

The natural design and coupling of biological structures are the root of realizing the high strength, toughness, and unique functional properties of biomaterials. Advanced architecture design is applied to many materials, including metal materials, inorganic nonmetallic materials, polymer materials, and so on. To improve the performance of advanced materials, the designed architecture can be enhanced by bionics of biological structure, optimization of structural parameters, and coupling of multiple types of structures. Herein, the progress of structural materials is reviewed, the strengthening mechanisms of different types of structures are highlighted, and the impact of architecture design on the performance of advanced materials is discussed. Architecture design can improve the properties of materials at the micro level, such as mechanical, electrical, and thermal conductivity. The synergistic effect of structure makes traditional materials move toward advanced functional materials, thus enriching the macroproperties of materials. Finally, the challenges and opportunities of structural innovation of advanced materials in improving material properties are discussed.
