MagPiezo: A Magnetogenetic Platform for Remote Activation of Endogenous Piezo1 Channels in Endothelial Cells

Advanced Functional Materials, Volume 36, Issue 31, 16 April 2026.
MagPiezo enables wireless activation of endogenous Piezo1 channels without genetic modification using 19 nm magnetic nanoparticles and low‐intensity magnetic fields. It generates torque forces at the piconewton scale to trigger mechanotransduction in endothelial cells, standing as a novel platform to interrogate and manipulate Piezo1 activity in vitro.

Porous Hybrid Soft Actuators From Liquid Crystal Networks and Lyotropic Chromonic Liquid Crystal Templated Hydrogels

Advanced Materials, Volume 38, Issue 24, 27 April 2026.
The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing

Advanced Functional Materials, Volume 36, Issue 26, 30 March 2026.
A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...

Design and Analysis of Coaxial Magnetic Gear Mechanism with Halbach Permanent-Magnet Array

Journal of Physics: Conference Series, 2019
Abstract The disadvantages of mechanical gear can be replaced by the advantages of magnetic gear related to transferring torque without mechanical touch, no gear lubrication, low mechanical loss, low vibration, and intrinsic overload protection. From the types of magnetic gear, coaxial magnetic gear is the most developed type.

Magnetic Field Analysis of Multi‐Segment Modulated Pole Motors Based on the Air Gap Domain Multi‐Harmonic Method

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
A subdomain analytical model for multi‐harmonic air‐gap subdomains is proposed to predict motor magnetic fields containing complex harmonic components. Theoretical analysis demonstrates that this model effectively reduces the matrix dimension during analytical computation, resulting in lower computational time costs for the same harmonic order while ...
