In-ear device for measuring brain activity

An in-ear measurement device like the one ESA astronaut Andreas Mogensen will use during his Huginn mission.

Researchers from Aarhus University, Denmark, have developed a small in-ear measuring device that Andreas will wear while sleeping on the Space Station. Similar to in-ear headphones, this device will measure the electroencephalogram (EEG) of Andreas’s brain, allowing researchers to analyse his brain activity throughout the night to help understand the quality of his sleep.
