Shape fixity ratio
Webb10 mars 2024 · With this system, we achieved good to excellent shape fixity ratios (50–90%) and excellent shape recovery ratios (∼100%, almost instantaneously) at body temperature (37 °C). Cytocompatibility tests demonstrated good viability either with cells on top or encapsulated during all shape memory processes. Webb18 mars 2024 · In addition, EPSis show good thermadapt shape memory behaviours (the shape retention ratio is 80.5–86.3%, the shape fixity ratio is 97.1–98.9%, and the shape recovery ratio is 95.6–99.8%), and they can convert from planar films into various shapes such as a “six-claw stool”, “wave-like rocking chair”, “windmill” and “paper airplane” under …
