Microfabricated magnetometers for imaging and communication

摘要

Sensors based on optically-pumped magnetometers allow the development of room-temperature, wearable imagingsystems for biomagnetism detection due to their excellent sensitivity, with applications such as Magnetoencephalographyand Brain-Computer Interfaces. The small size of sensors based on microfabricated vapor celltechnology promises high spatial resolution. The high sensitivity also opens up the possibility to use OPM sensorsin other applications such as Very Low Frequency communications and ultrasensitive microwave detection.
