TL;DR: A soft, elastomeric valve that contains a bistable membrane, which acts as a mechanical “switch” to control air flow, enables a gripper to grasp a ball autonomously and autonomous earthworm-like locomotion using an air source of constant pressure.

TL;DR: In this article, the authors report experiments with Cu films deposited on polymeric substrates and show that the rupture strains of the metal films are sensitive to their adhesion to the substrates, and well-bonded Cu films can sustain strains up to 10% without appreciable cracks and up to 30% with discontinuous microcracks.

TL;DR: In this paper, the authors measured the curvature change upon the removal of a thin film, and found the magnitude of the residual stress to be 610 MPa in a separate experiment, and simultaneously recorded the capacitance change of the film.

TL;DR: In this paper, the authors characterized and ranked the energy of various periodic mode patterns, including checkerboard, hexagonal and herringbone, in terms of the extent to which they reduce the elastic energy of the compliant elastic substrate.

TL;DR: In this article, a theory that couples large amounts of lithiation and deformation is proposed to analyze the deformation of a small element of an electrode under stresses, and the theory is combined with a diffusion equation to analyze a spherical particle of a battery being charged and discharged at a constant rate.
