4D printing of trigger-free shape-memory hydrogels towards self-adaptive substrates for bioelectronics [PDF]

Nature Communications
Shape-changing smart substrates are revolutionizing implantable bioelectronics by offering minimal invasiveness and self-adaptive geometric conformity. However, precise manipulation of shapeshifting, which is critical for the successful implantation, are

Surface Deformation Models for Nonrigid 3D Shape Recovery [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2007
Three-dimensional detection and shape recovery of a nonrigid surface from video sequences require deformation models to effectively take advantage of potentially noisy image data. Here, we introduce an approach to creating such models for deformable 3D surfaces.

Template-Based Monocular 3D Shape Recovery Using Laplacian Meshes [PDF]

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2016
We show that by extending the Laplacian formalism, which was first introduced in the Graphics community to regularize 3D meshes, we can turn the monocular 3D shape reconstruction of a deformable surface given correspondences with a reference image into a much better-posed problem.

Shape-Memory Properties of 3D Printed Cubes from Diverse PLA Materials with Different Post-Treatments

Technologies, 2021
Poly(lactic acid) (PLA) belongs to the 3D printable materials which show shape-memory properties, i.e., which can recover their original shape after a deformation if they are heated above the glass transition temperature.
