MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

Advanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Pixelation‐Free, Monolithic Iontronic Pressure Sensors Enabling Large‐Area Simultaneous Pressure and Position Recognition via Machine Learning

Advanced Functional Materials, EarlyView.
A pixelation‐free, monolithic iontronic pressure sensor enables simultaneous pressure and position sensing over large areas. AC‐driven ion release generates spatially varying impedance pathways depending on the pressure. Machine learning algorithms effectively decouple overlapping pressure–position signals from the multichannel outputs, achieving high ...

External Reflection From Two‐Photon Laser‐Printed Micromirrors Enables Photomechanical Actuation at a 90° Incident Angle

Advanced Functional Materials, EarlyView.
Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Two‐Way Shape Memory Alloy and Polymer Composite Hybrid Smart Actuator With High Speed, Accuracy, and Reversible Deformation

Advanced Functional Materials, EarlyView.
Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can
