Investigation of Wrinkling Initiation in Shear Spinning [PDF]
MATEC Web of ConferencesMetal spinning is a flexible and net-shape sheet forming process however its process development still heavily relies on empirical knowledge to determine process parameters to avoid processing failures, such as wrinkling.

Bioinspired Multiscale Wrinkling Patterns on Curved Substrates: An Overview
Nano-Micro Letters, 2020 The surface wrinkling of biological tissues is ubiquitous in nature. Accumulating evidence suggests that the mechanical force plays a significant role in shaping the biological morphologies.

The skin-wrinkling test: principles and clinical applications [PDF]
Arquivos de Neuro-PsiquiatriaCutaneous wrinkling is a normal phenomenon that occurs on the palms in a reversible manner and results from vasoconstriction influenced by vasomotor function.

Structural Analysis of Thin Film with Applied Pre-Strain in Substrate [PDF]
한국정밀공학회지, 2023 Stretchability enables the device to be patched to a curved surface or to be folded several times to maximize usability. Among many methods, the pre-strain method is advantageous in that the stretchability as much as the pre-strain applied to the ...

Flange Wrinkling in Deep-Drawing: Experiments, Simulations and a Reduced-Order Model
Journal of Manufacturing and Materials Processing, 2022 Flange wrinkling is often seen in deep-drawing process when the applied blankholding force is too small. This paper investigates the plastic wrinkling of flange under a constant blankholding force.

All-Polymer Printed Low-Cost Regenerative Nerve Cuff Electrodes
Frontiers in Bioengineering and Biotechnology, 2021 Neural regeneration after lesions is still limited by several factors and new technologies are developed to address this issue. Here, we present and test in animal models a new regenerative nerve cuff electrode (RnCE).

Water-induced finger wrinkles do not affect touch acuity or dexterity in handling wet objects. [PDF]
PLoS ONE, 2014 Human non-hairy (glabrous) skin of the fingers, palms and soles wrinkles after prolonged exposure to water. Wrinkling is a sympathetic nervous system-dependent process but little is known about the physiology and potential functions of water-induced skin
