“…As we used the same concentration of GelMA in the layers for myofiber and fibroblast stimulation, we could also prevent a potential delamination issue caused by interfaces between two hydrogels with significantly different mechanical properties. [ 31 ]…”

Skeletal muscle connective tissue (MCT) surrounds myofiber bundles to provide structural support, produce force transduction from tendons, and regulate satellite cell differentiation during muscle regeneration. Engineered muscle tissue composed of myofibers layered within MCT has not yet been developed. Herein, a bioengineering strategy to create MCT‐layered myofibers through the development of stem cell fate‐controlling biomaterials that achieve both myogenesis and fibroblast differentiation in a locally controlled manner at the single construct is introduced. The reciprocal role of transforming growth factor‐beta 1 (TGF‐β1) and its inhibitor as well as 3D matrix stiffness to achieve co‐differentiation of MCT fibroblasts and myofibers from a human‐induced pluripotent stem cell (hiPSC)‐derived paraxial mesoderm is studied. To avoid myogenic inhibition, TGF‐β1 is conjugated on the gelatin‐based hydrogel to control the fibroblasts’ populations locally; the TGF‐β1 degrades after 2 weeks, resulting in increased MCT‐specific extracellular matrix (ECM) production. The locations of myofibers and fibroblasts are precisely controlled by using photolithography and co‐axial wet spinning techniques, which results in the formation of MCT‐layered functional myofibers in 3D constructs. This advanced engineering strategy is envisioned as a possible method for obtaining biomimetic human muscle grafts for various biomedical applications.

“…There are two different basic types of natural oscillation mode; out-of-plane and in-plane modes. The out-of-plane oscillation caused by transverse waves is closely related to bending stiffness of the plate, whereas the in-plane oscillation caused by longitudinal waves is related to its in-plane stiffness, i.e., tensile/compressive stiffness [10]. The out-of-plane oscillations are classified furthermore into three types: symmetric, antisymmetric, and complex (symmetric-antisymmetric) modes, depending on the symmetry of the oscillation shape [17] as well as the in-plane oscillations [18].…”

“…The natural frequency, however, also depends on the density, geometry, and defects [7][8][9][10]. Figure 9a illustrates the natural frequencies of mode 19 (out-of-plane) of Model A calculated with variations of Young's modulus E 1 and density q 1 of Layer 1.…”

“…The present results demonstrate that elastic property of a thin-layer on a substrate can be determined using a plain laminate sample regardless of residual stress and the residual stress can be determined using a laminate sample with a semi-hole. The natural frequency, however, also depends on the density, geometry, and defects [7][8][9][10]. Figure 9a illustrates the natural frequencies of mode 19 (out-of-plane) of Model A calculated with variations of Young's modulus E 1 and density q 1 of Layer 1.…”

“…Resonant ultrasound spectroscopy (RUS) has been developed as a non-destructive testing method for determination of accurate elastic constants and in addition also for defect inspection [7][8][9][10]. The RUS utilizes the resonant oscillations of sample, which basically depend on geometry, density, and elastic property.…”

Elastic properties and residual stresses are critical for the assessment of the reliability of ceramics components. The thin electrolyte layer of anode supported SOFCs is under a state of high compressive residual stress. In the present study, the elastic properties of this layer as well as the residual stress distribution induced in the anode‐supported planar SOFC cell were examined by using the resonant ultrasound spectroscopy (RUS). A modal analysis by finite element simulation demonstrated that the RUS has a great potential to determine these mechanical characteristics. The Young's modulus can be determined from the natural frequencies of the layered sample whilst the residual stress can be determined using the sample with a semi‐hole. Estimates of the Poisson's ratio are possible. In the experiment, various individual resonant oscillations were successfully identified using the present RUS system. Hence, by comparison of experimental results and simulations, the elastic properties as well as the residual stress were obtained. Although the proposed method is still experimentally challenging, it could be developed to become a powerful tool to simultaneously determine residual stresses and elastic constants of thin‐layered systems.
