Advanced Intelligent Systems, EarlyView.Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...

Compliant Footpads Enable Terrain‐Adaptive Hopping in a Monopedal Robot
Advanced Intelligent Systems, EarlyView.A lightweight compliant footpad with embedded spines lets a monopedal hopping robot keep stable ground contact. It preserves stance‐phase dynamics and enables reliable hopping on rock, sand, and ice. Monopedal hopping robots offer exceptional mobility over discontinuous terrain but require consistent foot‐ground contact to maintain stance‐phase ...

Spin Transport in Thin Copper Channels Fabricated via Thermal Scanning Probe Lithography
Advanced Physics Research, EarlyView.Thermal scanning probe lithography (t‐SPL) is demonstrated as an alternative to electron‐beam lithography for fabricating all‐metallic non‐local spin valves with ∼100 nm features. Devices exhibit strong spin signals and clean magnetic switching, demonstrating the viability of t‐SPL for nanoscale spintronics.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats
The Anatomical Record, EarlyView.Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Overcoming spectral limits of perovskite photodetectors for the infrared region
InfoScience, EarlyView.Infrared (IR) photodetectors are vital for modern optoelectronics, but traditional inorganic semiconductors face limitations in cost, processing, and bandgap tunability. This review provides a summary of advanced strategies to extend metal halide perovskites into the IR region, categorizing approaches into intrinsic material engineering, physical ...
