Dynamic Modelling and Experimental Investigation of an Active–Passive Variable Stiffness Actuator

Actuators
To overcome the limitations imposed by the low flexible angle of conventional robots, an active–passive variable stiffness elastic actuator (APVSA) is investigated and a nonlinear dynamic model for the APVSA is established, considering the factors of the

Architected Bio‐Based Iontronic Skin With Dual‐Mode Pressure and Strain Sensing

Advanced Functional Materials, EarlyView.
Bio‐based acrylates in combination with an ionic liquid create 3D‐printed ionogels with compositionally tuneable mechanics and ionic conductivity. Gyroid architectures amplify low‐pressure sensitivity while preserving robust strain sensing, enabling dual‐mode detection of pressure and deformation.

High‐Modulus Skeleton‐Reinforced PDMS Microstamps for Precision Transfer Printing of Microscale Devices

Advanced Functional Materials, EarlyView.
Elastomeric micropillars bend under contact loading, sliding microscale devices out of alignment during transfer printing. A hybrid PDMS stamp embeds a high‐modulus skeleton within each pillar while retaining a compliant contact surface. The reinforcement confines pillar deformation, suppressing interfacial sliding and preserving array registration on ...

Biohybrid Crawling Robot With Spiral‐Spring Backbone and Inclined Legs for Enhanced Locomotion

Advanced Materials, EarlyView.
We present a biohybrid crawling robot integrating a muscle ring with a flexible skeleton combining two complementary structural elements. The spiral‐spring backbone enables large‐amplitude bending without compromising axial stability, while outward‐inclined legs with unequal front–rear lengths effectively convert deformation into directional strides ...
