Clinical electroencephalography (EEG) is an important test in the care of many patients in hospital – from people who are mildly confused, or those seizures or having “funny turns”, to those who are completely unresponsive. Clinical EEG safely and without harm records “brain waves” (the electrical activity of the brain) from about 20 sensors, called electrodes, temporarily stuck to the scalp with glue or paste. A clinical EEG takes about 15 minutes to set up and 30 minutes to record.
By studying the brain waves recorded from an EEG, a specialist can try and work out what is happening in the brain to cause a patient’s problem. However, EEG is poorly available in hospitals, needing expensive equipment and specialists to record and interpret.
In this study the researchers are interested in making a new kind of EEG recording device which can simply record electrical brain activity from within the ear canal, and without the need for glue or paste. This could make EEG far more available and easier to use because such a device could be quickly and easily inserted without the need for expensive equipment, scalp electrodes, or specialist training.
However, to understand if such a future device is possible, the researchers first need to record “in-ear” EEG signals, i.e., via electrodes not placed on the scalp as normal, but rather placed in the ear canals using an 'ear plug' style electrode built into a soft ear plug. Then, at the same time, the researchers want to record standard clinical EEG from the scalp, and then later compare the two recordings.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

08 Jan 2024 30 Apr 2024

During the standard clinical EEG, the researchers will additionally record from the ear canals using a safe and harmless in-ear EEG electrode/sensor. The clinical EEG records from electrodes attached to the skull using glue or paste. The recordings are obtained by an “ear plug” device inserted into the ears at the same time. The in-ear electrodes are single-use only.


Any patient aged 18 years and over referred to an inpatient EEG
