Device Could Spot Seizures by Reading Brainwaves through the Ear

Picking up signals: A custom earpiece with three electrodes records from within the hearing canal.

Neuroscientists often use electroencephalography (EEG) as an inexpensive way to record electrical signals in the brain. Though it would be useful to run these recordings for long periods of time, that usually isn’t practical: EEG recording traditionally involves attaching many electrodes and cables to a patient’s scalp.

Now engineers at Imperial College in London have developed an EEG device that can be worn inside the ear, like a hearing aid. They say the device will allow scientists to record EEGs for several days at a time; this would allow doctors to monitor patients who have regularly recurring problems like seizures or microsleep.

“The ideal is to have a very stable recording system, and recordings which are repeatable,” explains co-creator Danilo Mandic. “It’s not interfering with your normal life, because there are acoustic vents so people can hear. After a while, they forget they’re having an EEG.”
