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.

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 ...

A Halbach array magnetic gear for auxiliary drives
Vestnik IGEUA diesel locomotive must drive a significant number of units with different rated rotation speeds from a single diesel engine with minimal energy consumption. The mechanical and hydraulic drives currently in use demand high maintenance and specific oil quality, while electric drives are bulky and have lower efficiency.

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 637-646, January 2026.Abstract Purpose One of the intrinsic limitations of low‐field MRI is low signal‐to‐noise ratio, which can be further reduced by electromagnetic interference (EMI) due to the lack of a Faraday shielded room. To address this issue, we propose a novel radiofrequency (RF) coil design that is inherently less sensitive to EMI while maintaining high receive ...

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 ...

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This paper investigates the impact of sleeve segmentation on eddy‐current loss in permanent‐magnet (PM) machines with fractional‐slot concentrated‐windings (FSCW) under different stator MMF harmonics. The concept of equivalent sleeve segmentation is introduced.
