Artificial bionic skin material is playing an increasingly important role in the field of medicine and bionic engineering and becoming a research hotspot in many disciplines in recent years. In this work, the digital moiré method was used to measure the mechanical field of the bionic skin material under different suturing conditions. Through the digital image process, the deformation characteristics and the stress distribution near the contact area between the bionic skin material and the suture were obtained and discussed. The different healing effects caused by suturing mode were further explored, which can provide mechanical guidance for wound suturing in clinical medicine.
人工仿生皮肤材料在医学和仿生工程领域发挥着越来越重要的作用，近年来成为许多学科的研究热点。在这项工作中，采用数字莫尔条纹法测量了不同缝合条件下仿生皮肤材料的力学场。通过数字图像处理，获得并讨论了仿生皮肤材料与缝线接触区域附近的变形特性和应力分布。进一步探讨了缝合方式引起的不同愈合效果，可为临床医学中的伤口缝合提供力学指导。
