Soft Robots Proprioception Through Stretchable Laser‐Induced Graphene Strain Sensors

Advanced Intelligent Systems, EarlyView.
This study demonstrates the potential of laser‐induced graphene and silicone sensors for soft pneumatic grippers’ proprioception. The sensors are thin, stretchable, mechanically transparent, and easy to integrate. Finite‐element method analysis identifies the finger's neutral bending plane and four sensor positions are tested to validate the ...

Azobenzene‐Oxindole Photochromic Dyads

Angewandte Chemie, EarlyView.
A novel photochromic azobenzene‐oxindole dyad is reported. The combination of the two switches promotes drastic molecular geometry changes and allows for precise NMR quantification. This enables the study of the photokinetic behavior under different irradiation conditions and the discovery of a unique photokinetic relationship between the two ...

Tunable Mechanism Enables Robust Surface Perching Under Different Landing Impacts and Orientation Misalignment

Advanced Intelligent Systems, EarlyView.
A passive, tunable perching mechanism enables aerial robots to reliably perch onto smooth surfaces. The design integrates a bistable mechanism with a soft suction cup and SMA actuators for active tuning. Experiments demonstrate robust performance by adapting to varying contact speeds and surface orientation misalignments, enabling diverse perching ...

Supramolecular Gels as Active Tools for Reaction Engineering

Angewandte Chemie, EarlyView.
The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

Roadmap to Nanomedical Applications: Nanotoxicology and In Vitro Guidelines for Lanthanide‐Doped Luminescence Nanothermometers

Advanced NanoBiomed Research, EarlyView.
Lanthanide‐based luminescence nanothermometry holds multifaceted potential for nanomedical applications, yet despite significant research advances, clinical translation of the engineered nanomaterials is still controversial and widely disputed. This is related to crucial nanotoxicological aspects that must be addressed at the preclinical level ...

Predator–Prey Behavior of Droplets Propelling Through Self‐Generated Channels in Crystalline Surfactant Layers

Angewandte Chemie, EarlyView.
A crystalline layer is formed by an amphiphilic decylamine surfactant at the air/water interface. Aldehyde‐containing ester oil droplets self‐propel by consuming amines from the crystalline layer, thereby generating open channels along which myelin‐forming amphiphile droplets chase and ultimately catch the aldehyde droplets in a predator–prey analogy ...
