Toward Perception‐Native Electronic Skin: Bio‐Inspired In‐/Near‐Sensor and Neuromorphic Computing for Humanoid Robots

Advanced Materials Technologies, EarlyView.
Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

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.

Dynamic Fluorescence Modulation via Light‐Driven Competitive Protonation

Advanced Optical Materials, EarlyView.
A two‐component molecular system demonstrates reversible, light‐driven fluorescence write–erase cycling and thermal imaging. Illumination of a merocyanine photoacid transfers a proton to a highly efficient fluorescent pyridinium dye, switching its emission color; thermal relaxation reverses the process in the dark.

Rigid Boron‐Fused Frameworks for Efficient Near‐Infrared Emission and Optical Gain Beyond 900 nm

Advanced Optical Materials, EarlyView.
Multiple‐resonance (MR)‐derived boron‐fused frameworks were integrated into narrow‐gap, long‐range charge‐transfer emitters to reduce structural relaxation and electron‐vibrational coupling. This strategy significantly decreases nonradiative losses, leading to improved near‐infrared (NIR) luminescence efficiency and low‐threshold amplified spontaneous ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Design of a 7 DOF force-torque sensor for a master device with a pinching action

, 2015
This paper proposes a 7 DOF force-torque (F/T) sensor with 16 strain gauges for the master device with a pinching capability. It is necessary to measure the force and torque at the master device to render high-fidelity haptic feedback.
