Mini-Sensor Measures Brain Activity

Physicists have developed tiny, portable sensors that can detect our brain's electromagnetic waves.



Typically, machines that measure electromagnetic fields in the brain are bulky, difficult to move, and temperature-controlled. Now, physicists have come up with a simpler way to measure these fields.

The mini-sensors in the video above eliminate many of the disadvantages of typical machines. In the future, they may prove useful for on-site evaluations of brain injuries, such as on a football field.
