New Publication in Nanoscale

Our new paper, in collaboration with Dr. Minxiang Zeng, titled “Nontraditional Granular Magnetoresistive Devices: A Short Review” is published in Nanoscale.

In this work, we review the rapid evolution of non-traditional granular magnetoresistive (MR) devices as a promising alternative to conventional thin-film MR sensors. The article highlights how advances in nanoparticle engineering, insulating matrices, and polymeric binders enable cost-effective, scalable, and mechanically flexible magnetoelectronics suitable for wearable and curved platforms. We discuss the underlying physical mechanisms, material systems, fabrication strategies, and performance trends of granular MR devices over the past two decades, with a particular focus on improving sensitivity for low-field and biomagnetic sensing. This review outlines key opportunities and remaining challenges for translating granular MR systems into next-generation flexible and printable spintronic technologies.
