The challenge to develop grafts for tissue regeneration lies in the need obtain a scaffold that will promote cell growth order form new at trauma-damaged site. Scaffolds also provide compatible mechanical properties support and facilitate desired physiological activity. Here, we used natural materials bio-composite made of unique collagen embedded an alginate hydrogel material. fibers create building blocks exhibited hyper-elastic behavior similar human tissue. prominent properties, along...
Abstract 3D-printable conductive polymers are gaining remarkable attention for diverse applications, including wearables, pressure sensors, interference shielding, flexible electronics, and damage identification. However, the relationship between anisotropy of their mechanical electrical properties remains rather unexplored. This study focuses on characterizing Polylactic Acid/Carbon Black nanocomposites manufactured through Fused Filament Fabrication. It aims to investigate effect...
The annulus fibrosus (AF) of the intervertebral disc (IVD) consists a set concentric layers composed primary circumferential collagen fibers arranged in an alternating oblique orientation. Moreover, there exists additional secondary radial translamellar which connects layers, creating interconnected fiber network. aim this study was to investigate mechanical role Toward that goal, three-dimensional (3D) finite element model L3-L4 spinal segment generated and calibrated axial compression pure...
Complex interfaces that involve a combination of stiff and compliant materials are widely prevalent in nature. This creates superior assemblage with strength toughness. When combining two different large stiffness variations, an interfacial stress concentration is created, decreasing the structural integrity making structure more prone to failure. However, nature frequently combines dissimilar properties. Additive manufacturing (AM) 3D printing have revolutionized our engineering...
Abstract Intervertebral disc (IVD) degeneration and accompanying lower back pain impose global medical societal challenges, affecting over 600 million people worldwide. The IVD complex fibrocartilaginous structure is responsible for the spine biomechanical function. nucleus pulposus (NP), composed of swellable glycosaminoglycan (GAG), transfers compressive loads to surrounding fiber‐reinforced annulus fibrosus (AF) lamellae, which stretches under tension. Together, these substructures allow...
Multiscale micro–nano fibrous structures are a cutting-edge research area in material science and have drawn the attention of scientists recent years. These widely distributed nature's materials hold fascinating unique properties, such as mechanical behaviors, high surface to volume ratio, special multiscale biological functionalities. Herein, we demonstrate step-by-step biomimetics composite system influence different structural mechanisms on behavior. This is done using systematic...
Plant tissues are constructed as composite material systems of stiff cellulose microfibers reinforcing a soft matrix. Thus, they comprise smart and multifunctional structures that can change shape in response to external stimuli due asymmetrical fiber alignment possess robust mechanical properties. Herein, we demonstrate the biomimetics plant system using silk fiber-reinforced alginate hydrogel matrix biocomposites. We fabricate single bilamellar biocomposites with different orientations....
Anterior cruciate ligament (ACL) ruptures are prevalent knee injuries, with approximately 200,000 annually, and treatment costs exceed USD two billion in the United States alone. Typically, initial detection of ACL tears anterior tibial laxity (ATL) involves manual assessments like Lachman test, which examines laxity. Partial can go unnoticed if they minimally affect laxity; however, will progress to a complete tear requiring surgical treatment. In this study, computational finite element...
Natural materials often consist of hierarchical architectures, which are extremely efficient in mechanical terms.Whereas the structure-function relationship is well-studied natural hard materials, soft not getting equal attention, despite their high prevalence nature.These usually constructed as fiber-reinforced composites consisting diverse structural motifs that result an overall unique behavior.In this study, a proof-of-concept, biomimetic composite was fabricated from electrospun...
