Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing
Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Novel multifunctional materials based on ionic liquids: on demand micro-valve actuation for lab-on-a-chip applications [PDF]
We present the fabrication, characterization and performance as a micro-valve of four novel materials, ionogels, consisting in a polymeric structure with benzospiro-pyran units and phosphonium based ionic liquids. Each inonogel is photopolymerised in the

Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives
A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

Meta‐Rod Mechanical Metamaterials With Programmable Reconfiguration
Existing mechanical metamaterials achieve programmable large deformations in planar square or cubic configurations, restricted by required complex boundary conditions. This research proposes a 1D metamaterial, Meta‐rod, with linear, bending, twisting, area, and volume deformation modes.
