Abstract

Scanning Acoustic Microscopy (SAM) has become a vital tool in materials science and biology, allowing for non-destructive and non-invasive analysis of biological specimens and bio-inspired materials. Its deep-penetrating imaging capabilities enable a broad range of applications. This study combines SAM with Singular Spectral Analysis (SSA) to enhance signal processing and extract key data, particularly acoustic impedance. Reindeer antlers, known for their rapid growth and unique mechanical properties, were chosen as a focus for this method. SAM was used to quantify the specific acoustic impedance, longitudinal stiffness, bulk modulus, and Young's modulus of the material at three orientations (0°, 45°, and 90°). This analysis provides a comprehensive understanding of the directional dependence of its structural behavior, highlighting its orthotropic nature. By analyzing cross-sections along three axes, this study reveals the orthotropic biomechanical properties of reindeer antlers, offering a systematic approach to characterizing biological materials. Their unique strength, resilience, and rapid growth highlight their potential as a sustainable and innovative biomaterial for bioengineering and advanced composites.

使用奇异光谱分析的扫描声学显微镜对驯鹿鹿角进行生物力学表征

扫描声学显微镜（SAM）已成为材料科学和生物学的重要工具，允许对生物标本和生物启发材料进行非破坏性和非侵入性分析。其深穿透成像能力使其应用范围广泛。该研究将SAM与奇异谱分析（SSA）相结合，以增强信号处理和提取关键数据，特别是声阻抗。驯鹿角以其快速生长和独特的机械性能而闻名，被选为该方法的重点。使用SAM量化材料在三个方向（0°、45°和90°）的比声阻抗、纵向刚度、体积模量和杨氏模量。这种分析提供了对其结构行为的方向依赖性的全面理解，突出了其正交异性的性质。本研究通过对三轴截面的分析，揭示了驯鹿鹿角的正交异性生物力学特性，为生物材料的表征提供了系统的方法。其独特的强度，弹性和快速增长突出了其作为生物工程和先进复合材料的可持续和创新生物材料的潜力。

期刊介绍： BONE is an interdisciplinary forum for the rapid publication of original articles and reviews on basic, translational, and clinical aspects of bone and mineral metabolism. The Journal also encourages submissions related to interactions of bone with other organ systems, including cartilage, endocrine, muscle, fat, neural, vascular, gastrointestinal, hematopoietic, and immune systems. Particular attention is placed on the application of experimental studies to clinical practice.
