Detection of Fetal Arrhythmia by Using Optically Pumped Magnetometers
JACC: Clinical Electrophysiology, 2018 Fetal magnetocardiography (fMCG) is an emerging technology that has provided invaluable insight into the mechanisms of fetal arrhythmia. Its efficacy for diagnosis and management of serious fetal arrhythmia has been acknowledged in the recent American Heart Association Statement on Diagnosis ...

3D‐Printed Giant Magnetoresistive (GMR) Sensors Based on Self Compliant Springs
Advanced Engineering Materials, Volume 28, Issue 8, 22 April 2026.This work explores 3D‐printed GMR sensors utilizing self‐compliant spring structures and conductive PLA composites. By optimizing arm width, we achieved high piezoresistive (0.34%/mm) and magnetoresistive (0.77%/mT) sensitivities. Demonstrated through Bluetooth‐integrated pressure and magnetic position sensing, these full printed low‐cost, customizable

Investigation of the intrinsic sensitivity of a ³He/Cs magnetometer [PDF]
, 2016 We report on extensive studies on the intrinsic sensitivity of a combined ³He/Cs magnetometer. The magnetometer relies on the detection of the free spin precession of nuclear spin polarized ³He by optically pumped cesium magnetometers.

Contact Lens with Moiré Patterns for High‐Precision Eye Tracking
Advanced Functional Materials, Volume 36, Issue 29, 9 April 2026.This work presents a passive contact lens for high‐precision eye tracking, integrating a microscopic moiré grating label. The parallax‐induced shift of macroscopic moiré patterns enables angle measurement with 0.28° precision using a standard camera under ambient light.

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Advanced Materials, Volume 38, Issue 20, 7 April 2026.Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Advanced Materials Interfaces, Volume 13, Issue 8, 21 April 2026.A near‐infrared photosensitizer that facilitates efficient solid‐state photon upconversion by recycling triplets formed within a fullerene‐based donor–acceptor bulk‐heterojunction system is demonstrated. Spectroscopic investigations reveal that the energy of photogenerated charge transfer states of triplet character (3CT) is subsequently transferred to

Advanced Electronic Materials, Volume 12, Issue 8, 20 April 2026.The VO2 layer is found to be a tunable orbital current source. The damping‐like spin–orbit torque efficiency is significantly enhanced across VO2’s metal‐insulator transition temperature in the VO2/Pt/Co/Pt multilayers, leading to 60% reduction in the power consumption of magnetization switching, which paves the way for the development of energy ...

Annals of Neurology, Volume 99, Issue 4, Page 1046-1058, April 2026.[Color figure can be viewed at www.annalsofneurology.org] Objective Sleep‐predominant network hyperexcitability is increasingly recognized as a potential disease‐accelerating comorbidity in Alzheimer's disease (AD). However, its prevalence and risk‐factors remain debated, largely due to cohort‐specific and methodological differences across studies.
