Wearable Magnetic Field Sensors for Flexible Electronics [PDF]

open access: yesAdvanced Materials, 2014
Highly flexible bismuth Hall sensors on polymeric foils are fabricated, and the key optimization steps that are required to boost their sensitivity to the bulk value are identified. The sensor can be bent around the wrist or positioned on the finger to realize an interactive pointing device for wearable electronics.

A Quantum-Based Microwave Magnetic Field Sensor [PDF]

open access: yesSensors, 2018
In this paper, a quantum-based method for measuring the microwave magnetic field in free space is presented by exploring atomic Rabi resonance in the clock transition of 133Cs. A compact cesium glass cell serving as the microwave magnetic field sensing head was used to measure the spatial distribution of microwave radiation from an open-ended waveguide
