The human body is controlled by electrical impulses in the brain, the heart and nervous system. These electrical signals create tiny magnetic fields, which doctors could use to diagnose various ...

Researchers have designed a new Optically Pumped Magnetometer (OPM) sensor for magnetoencephalography (MEG). The sensor is smaller and more robust in detecting magnetic brain signals and ...

The types of magnetic sensors that are currently available. How the magnetic sensors work. Applications for the different magnetic sensors. Position sensors enable a variety of functions and controls ...

Biomagnetism applications A novel magnetic gradiometer can record human brain activity and detect cardiac activity in the presence of external magnetic field disturbance. (Courtesy: ...

New MFxM magnetic proximity switches detect magnetic fields over large distances up to 60 mm. These sensors can be used effectively in applications where the target is located behind a wall of ...

Scientists at the University of Birmingham have developed a new sensor to measure weak magnetic signals in the brain, which has the potential to increase understanding of connectivity in the brain, ...
