Numerical Investigation of Halbach-Array-Based Flexible Magnetic Sensors for Wide-Range Deformation Detection [PDF]
SensorsFlexible magnetic tactile sensors hold great promise for wearable electronics and intelligent robotics but often suffer from limited strain range and complex magnetic field variations due to rigid-soft coupling between the Hall sensor and magnetic layer.

Sensing Magnetic Field with Light and Nanomechanics [PDF]
Conference on Lasers and Electro-Optics, 2021 We demonstrate an optical magnetic field sensor based on a metamaterial-microcavity. Actuation of the microcavity by the magnetic Lorentz force controls its reflectivity. Such sensors promise microscale spatial, millisecond temporal and microtesla magnetic field resolution.

Thickness Dependence of Superconductivity in Layered Topological Superconductor β-PdBi2
Nanomaterials, 2021 We report a systematic study on the thickness-dependent superconductivity and transport properties in exfoliated layered topological superconductor β-PdBi2. The superconducting transition temperature Tc is found to decrease with the decreasing thickness.
