Micro-Meso Scale Model of Electrospun Poly (Ester Urethane) Urea Scaffolds

Soft tissue engineering applications require accurate descriptions of native and engineered tissue microstructure and their contributions to global mechanical behavior [1–6]. Moreover, micro scale based mechanical models can be used to: (1) guide tissue engineering scaffold design, (2) provide a better understanding of cellular mechanical and metabolic response to local micro-structural deformations, and (3) investigate structural changes as a function of deformation across multiple scales. We present a novel approach to automatically collect micro-architectural data (fibers overlaps, fiber connectivity, and fiber orientation) from SEM images of electrospun poly (ester urethane) urea (PEUU)…
