Self‐Sealing Microneedles Improve Precision and Reduce Reflux in Subretinal Cell Transplantation

Advanced Materials Technologies, EarlyView.
Ultrafine 49G microneedles enable subretinal delivery of induced pluripotent stem cell‐derived retinal pigment epithelial cells through a 50 µm outer diameter tip. Compared with conventional 38G microcannulas, these microneedles reduce cell suspension reflux in a rabbit model, highlighting the potential of microinvasive delivery instruments to improve ...

Low‐Outgassing Liquid Metal–Silicone Composites for Multifunctional Space Applications

Advanced Materials Technologies, EarlyView.
Integrating liquid metal microdroplets into a space‐grade silicone creates a multifunctional composite while preserving its inherent flexibility and low‐outgassing behavior. The composite has 11×$\times$ higher thermal conductivity while remaining thermally stable and maintaining a total mass loss of ≤$\le$ 1% under thermal vacuum testing.

Parameter Investigation for Stamp Manufacturing of Complex 3D Geometries Using Nanoimprint Lithography

Advanced Materials Technologies, EarlyView.
Nanoimprint lithography can replicate complex 3D microstructures with undercuts using single‐layer polymer stamps of different elasticities. By combining experiments and simulations, T‐shaped geometries and suitable undercut radii were identified that minimize stress and defects during demolding.

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

Advanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Asymmetry in Skipping Enhances Viability Against Control Input Noise

Advanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...
