Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Pseudo‐Haptic Feedback: Multi‐Modal Approaches to Stiffness Perception and User Experience

Advanced Science, EarlyView.
Can visual deformation substitute for physical haptic feedback? In immersive VR, deformation‐based pseudo‐haptics enables stiffness discrimination comparable to wearable force feedback, while their combination yields the highest performance and presence without increasing workload.

Mechanism of Direct Acoustic Construction and Gradient Properties Tuning

Advanced Science, EarlyView.
Directed acoustic construction enables omnidirectional gradient tuning of fingerprint‐inspired microstructures. By investigating the DAC mechanisms, diamond particles are found to enhance acoustic physical, mechanical, and chemical effects, promoting acoustic curing and broadening the range of gradient property tuning.

Interfacial Polarization Dynamics of Nitrile Dipoles in Organic Synaptic Transistors for Acoustic Reservoir Computing

Advanced Science, EarlyView.
Interfacial nitrile dipoles unlock tunable memory in organic synaptic transistors through competing polarization and relaxation. Their finite time dynamics are directly harnessed for acoustic reservoir computing, delivering 97.17% spoken digit recognition, reliable speech emotion and snoring recognition, and an ultralow event energy of only 50 aJ ...

Temperature Dependence of Space Charge Retention in Bulk Acrylic

Advanced Science, EarlyView.
The temperature dependence of space charge stability in electron‐charged bulk acrylic is probed by thermal manipulation. Charge carrier mobility is observed to be phonon‐dependent, which can be restricted indefinitely below a critical temperature.

Gradient‐Oxidized Bacterial Cellulose for Self‐Sustained Soil Moisture Sensing

Advanced Science, EarlyView.
An asymmetric encapsulated bacterial cellulose device integrates a gradient‐oxidized BC framework with a LiCl‐doped Ecoflex hygroscopic layer, enabling self‐powered soil moisture monitoring through directional ion transport. The device sustains stable hydrovoltaic output, supports deep‐learning humidity classification, and fully biodegrades in soil ...

Salivary Citrate Deficiency Defines an Endogenous Dentin Remineralization Failure State Through Glandular MT1/2‐Zn2+‐ACO2 Dysregulation

Advanced Science, EarlyView.
Salivary citrate deficiency in early‐stage Sjögren's syndrome accompanies impaired dentin remineralization despite preserved salivary flow and mineral availability. Matched‐ion experiments reveal disrupted mineral organization and reduced dentin recovery at disease‐associated citrate levels.
