WebApr 4, 2024 · This study aims to increase the maximum stretch ratio of vertically stacked wavy circuits in stretchable devices. Various parameters of the stretching stack of wavy circuits have been studied in the literature, including the stacking distance, thickness of the wavy section, and tilting angle of the circuit. subwoofers for cars reviewsThe stretch ratio is used in the analysis of materials that exhibit large deformations, such as elastomers, which can sustain stretch ratios of 3 or 4 before they fail. On the other hand, traditional engineering materials, such as concrete or steel, fail at much lower stretch ratios. True strain See more In physics and continuum mechanics, deformation is the transformation of a body from a reference configuration to a current configuration. A configuration is a set containing the positions of all particles of the body.
