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.
