Bioinspired skin adhesives are promising alternatives to traditional glue‐based skin patches for use in various skin‐attachable devices. However, the typical nano‐/microfabrication of these bioinspired microstructures provides limited manufacturing freedom over their performance, constraining their versatility and customization for widespread use. In this study, a hybrid 3D printing approach for fabricating a permeable skin patch is developed with adhesive miniaturized octopus‐like suckers (AMOS) for biosignal monitoring. The design and geometrical influences are investigated on the adhesion strength under different skin conditions (i.e., dry, wet, and hairy), permeability, and durability as well as proposed a biocompatible, stretchable, highly permeable, reusable, and conformable biopatch. Unlike commercially available biopatches that use chemical adhesives, the adhesion strength of an AMOS patch is customizable, does not cause skin irritation, and is comfortable for the wearer when worn for extended durations. The biopatch is tested in electromyogram, electrooculogram, and electrocardiogram signal measurement during a hand‐cycling experiment over extended durations that confirms its potential in extreme sport events. In addition to biosignal monitoring, 3D‐printed AMOS patches have broad applicability across various skin‐interfacing devices, including glucose and sweat monitoring, drug delivery, and wound healing. This approach offers a promising and highly customizable manufacturing solution for unlocking next‐generation skin‐attachable technologies.

Interfaces play a critical role in modern structures, where integrating multiple materials and components is essential to achieve specific functions. Enhancing the mechanical performance of these interfaces, particularly their resistance to delamination, is essential to enable extremely lightweight designs and improve energy efficiency. Improving toughness (or increasing energy dissipation during delamination) has traditionally involved modifying materials to navigate the well‐known strength‐toughness trade‐off. However, a more effective strategy involves promoting non‐local or extrinsic energy dissipation. This approach encompasses complex degradation phenomena that extend beyond the crack tip, such as long‐range bridging, crack fragmentation, and ligament formation. This work explores this innovative strategy within the arena of laminated structures, with a particular focus on fiber‐reinforced polymers. This review highlights the substantial potential for improvement by presenting various strategies, from basic principles to proof‐of‐concept applications. This approach represents a significant design direction for integrating materials and structures, especially relevant in the emerging era of additive manufacturing. However, it also comes with new challenges in predictive modeling of such mechanisms at the structural scale, and here the latest development in this direction is highlighted. Through this perspective, greater durability and performance in advanced structural applications can be achieved.
