4D–Printed Photothermally Actuated Soft Microgripper on an Optical Fiber Tip for Biomedical Applications

Advanced Materials Technologies, EarlyView.
In this study, we developed a light–driven soft microgripper by 3D–printing a photo–crosslinkable, temperature–responsive hydrogel with embedded silver particles onto an optical fiber tip. The microgripper actuates via photothermal effects at cell culture temperature and can gently grasp spheroids without minimal damage, offering a compact, actuator ...

3D‐Printed Actuator Powered by Liquid Crystal Elastomer Muscles at the Water–Air Interface

Advanced Materials Technologies, EarlyView.
Soft robots for unstructured environments require responsive, durable actuators. Liquid crystal elastomers (LCEs) provide large reversible deformations under thermal or optical stimuli. Direct ink writing enables fabrication of LCE actuators integrated with silicone, with mesogen chemistry and oligomers optimized for printable inks.

Single‐Step Fabrication of Smart 3D Microstructures Exploiting Naphthopyrans as Photoinitiators and Photochromic Molecules

Advanced Optical Materials, EarlyView.
Naphthopyran–benzophenone compounds can act simultaneously as photoinitiators and photochromic molecules for two‐photon polymerization. Using a single‐step process, liquid photoresist is encapsulated within polymerized 3D microstructures, preserving reversible UV–vis photochromism after fabrication.
