Phase‐Change Alloys Enable Localized Reversible Stiffening and Actuation in Steerable Eversion Tip‐Growing Robots

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This work presents a tip‐growing eversion robot that uses phase‐changing alloys for reversible stiffening and localized actuation, achieving 43× stiffness modulation, 15× force amplification, and segmental steering. The system enables precise navigation and force delivery in constrained, tortuous pathways.

Controlling a leaky tap

, 1999
We apply the Ott, Grebogy and Yorke mechanism for the control of chaos to the analytical oscillator model of a leaky tap obtaining good results. We exhibit the robustness of the control against both dynamical noise and measurement noise.A possible way of

Toward personalizing prosthesis prescription: A take‐home study of three microprocessor‐controlled prosthetic knees: A randomized crossover study

PM&R, Volume 18, Issue 3, Page 288-304, March 2026.
Abstract Background Previous studies on microprocessor‐controlled prosthetic knees (MPKs) often investigate benefits of MPKs as a class of knees rather than clinically relevant differences between specific knees, despite their distinct features. Objectives To systematically evaluate and report outcomes associated with three commercially available MPKs ...

Structure-Enhanced Yield Stress of Magnetorheological Fluids [PDF]

, 2000
The yield stress of magnetorheological (MR) fluids depends on the induced solid structure. Since thick columns have a yield stress much higher than a single-chain structure, we improve the yield stress of MR fluids by changing the fluid microstructure ...

A Folding Magnetic Soft Sheet Robot With Real‐Time Reconfigurable Magnetization for Targeted Drug Delivery

SmartBot, Volume 2, Issue 1, March 2026.
Magnetic robots have the characteristics of small size, non‐cable drive and motion agility, but multi‐angle folding and real‐time reconfigurable magnetization are difficult to be integrated into small‐sized soft structures. Here, the authors propose a magnetic soft sheet robot based on the dynamic magnetization characteristics of magnetorheological ...

Rheology and microstructural evolution in pressure-driven flow of a magnetorheological fluid with strong particle-wall interactions [PDF]

, 2012
The interaction between magnetorheological (MR) fluid particles and the walls of the device that retain the field-responsive fluid is critical as this interaction provides the means for coupling the physical device to the field-controllable properties of

Micropatterned Surfaces with Unidirectional Wetting Properties for Liquid Transport

Small Structures, Volume 7, Issue 2, February 2026.
Micropatterned surfaces that guide droplets in a single direction are gaining attention for their role in liquid transport. This review explores how surface designs enable such behavior, from gravity‐driven flow to stimulus‐responsive movement. It also discusses fabrication techniques, design challenges, and emerging strategies to advance directional ...
