Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms

Advanced Materials Technologies, EarlyView.
3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...

Coating‐Free Nanoscratching for Liquid‐Crystal Alignment on PCB‐Compatible Millimeter‐Wave Reflective Unit Cells

Advanced Materials Technologies, EarlyView.
Direct nanoscratching with a 500 nm diamond lapping film creates groove‐guided liquid‐crystal alignment interfaces on PCB‐compatible Cu‐patterned RF substrates within minutes, eliminating polymer coating and high‐temperature baking. The coating‐free process enables optical/molecular alignment validation and voltage‐programmable 28 GHz reflection‐phase ...

Ultrathin and Flexible Organic Light‐Addressable Potentiometric Sensors

Advanced Materials Technologies, EarlyView.
The first ultrathin, fully organic, and flexible light‐addressable potentiometric sensor (LAPS) is demonstrated. With a thickness of only 2.3–2.9 µm, this standalone film offers sensitivity to electrolyte potential and stable performance for over 170 days.

Large Faraday Rotation in Liquid Crystals With Embedded Paramagnetic Ions (Cu2+, VO2+) at Room Temperature

Advanced Optical Materials, EarlyView.
Large Faraday rotation at room temperature is observed in thin films of discotic copper (Cu2+: 3d9) and vanadyl (VO2+: 3d1) enaminoketone complexes. The large Verdet constant originates from a high density of paramagnetic centers, metal‐ligand p−d hybridization and π orbitals involved in optical transitions (identified by DFT calculations), as well as ...

Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

Advanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.
