Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation
Advanced Materials Technologies, EarlyView.Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Stiffness‐Programmable Origami Robots With Tendon‐Driven Actuation via Multimaterial 3D Printing
Advanced Robotics Research, EarlyView.Motion diversity is achieved in a tendon‐driven origami robot through programmable stiffness rather than modified actuation. Multimaterial 3D printing embeds soft creases, modular inserts redirect identical tendon inputs into distinct behaviors, and variable‐stiffness inserts enable real‐time switching.

Advanced Robotics Research, EarlyView.WorMa is an amphibious undulatory robot that uses Center of Mass redistribution as the sole terrain adaptation mechanism. This mechanism is based on internal fluid mass redistribution through a pump‐driven latex balloon system that creates three profiles: head‐biased, balanced, and tail‐biased.

Active‐Site Photothermal Energy Utilization in PET Depolymerization
Angewandte Chemie, EarlyView.Photothermal catalysis enables efficient PET depolymerization, yet the role of active‐site temperature remains unclear. A catalytic activity reversal between Pd–CNG and PdPOM–CNG is observed under thermal and photothermal conditions. Efficient nanoscale photothermal energy delivery raises active‐site temperature, compensates for lower intrinsic ...
