OptoMagneticSensor

Nerve impulses, in traveling through the body, generate ultra-small magnetic fields which scientists at the Niels Bohr Institute (University of Copenhagen) have been able to detect and measure with an optical magnetic field sensor of caesium gas, which works at body temperature. The speed of nerve impulse transmission can indicate nerve damage, as with multiple sclerosis, and the device is sensitive enough to provide readings without direct contact with the body.   MORE
