Focal adhesion-mediated directional cell migration guided by gradient-stretched substrate [PDF]
iScienceSummary: Soft tissues experience strain under mechanical stresses, storing energy as residual stresses and strain energy. However, the specific impact of such strain on cell migration and its molecular mechanisms remains unclear.

Prestrain-Enabled Stretchable and Conductive Aerogel Fibers. [PDF]
Polymers (Basel)Aerogels combine ultralow density with high surface area, yet their brittle, open networks preclude tensile deformation and hinder integration into wearable electronics. Here we introduce a prestrain-enabled coaxial architecture that converts a brittle conductive aerogel into a highly stretchable fiber.

A Homogenized Bending Theory for Prestrained Plates
Journal of Nonlinear Science, 2022 AbstractThe presence of prestrain can have a tremendous effect on the mechanical behavior of slender structures. Prestrained elastic plates show spontaneous bending in equilibrium—a property that makes such objects relevant for the fabrication of active and functional materials. In this paper we study microheterogeneous, prestrained plates that feature

Effect of Prestrain on the Actuation Characteristics of Dielectric Elastomers [PDF]
Polymers, 2020 Dielectric elastomers (DEs) represent a class of electroactive polymers that deform due to electrostatic attraction between oppositely charged electrodes under a varying electric field. Over the last couple of decades, DEs have garnered considerable attention due to their much-coveted actuation properties.

Plates with Incompatible Prestrain [PDF]
Archive for Rational Mechanics and Analysis, 2016 We study the effective elastic behavior of incompatibly prestrained plates, where the prestrain is independent of thickness as well as uniform through the thickness. We model such plates as three-dimensional elastic bodies with a prescribed pointwise stress-free state characterized by a Riemannian metric $G$ with the above properties, and seek the ...

Preparation and Physical Properties of Stretchable FeRh Films with Periodic Wrinkle Structure
Advanced Materials Interfaces, 2023 Stretchable magnetic materials are highly desirable for developing flexible high‐performance magnetoelectronic devices. However, it is still challenge to fabricate stretchable magnetic films with high growth temperature.

Plates with incompatible prestrain of high order [PDF]
Annales de l'Institut Henri Poincaré C, Analyse non linéaire, 2017 We study the elastic behaviour of incompatibly prestrained thin plates of thickness h whose internal energy E^{h} is governed by an imposed three-dimensional smooth Riemann metric G

Curved Film Microstructure Arrays Fabricated via Mechanical Stretching
Micromachines, 2021 We report on curved film microstructure arrays fabricated through polydimethylsiloxane (PDMS) film buckling induced by mechanical stretching. In the process of the microstructure preparation, a PDMA film is glued on a bidirectionally prestretched PDMS ...

Heterogeneous growth-induced prestrain in the heart [PDF]
Journal of Biomechanics, 2015 Even when entirely unloaded, biological structures are not stress-free, as shown by Y.C. Fung׳s seminal opening angle experiment on arteries and the left ventricle. As a result of this prestrain, subject-specific geometries extracted from medical imaging do not represent an unloaded reference configuration necessary for mechanical analysis, even if the
