In-the-ear EEG devices designed in Aarhus in the group of Preben Kidmose.

Some time ago we (three DTU researchers) got in-the-ear EEG devices from the Preben Kidmose group in Aarhus. These devices are made via casting to fit the individual ears. Tiny electrodes wired to a small plug are fitted on the plastic shell. There is a hole in the shell, so sounds from the environment travels through to the ear drum.
