Caption: To achieve the heart's 3D motion, the team embedded their soft modified pneumatic artificial muscles -- made of silicone elastomer in a braided mesh -- in a matrix also made of soft silicone elastomer. The top images show the team's heart prototype as it is subjected to various pressures. The middle images show a computer model of the mesh only as it deforms at corresponding pressures, and below is a computer model showing how the pneumatic artificial muscles and mesh change their motion in response to the different pressure regimes. The U indicates displacement.
