PenEEG

Our PenEEG is a portable device that provides EEG signals within minutes of setting it up. In the hospital, neurologists have to wait for an EEG technician to set up the EEG to collect signals from the patients, which can take anywhere from thirty minutes to hours. The current EEG devices on the market require thirty to seventy minutes for setup [1] , which makes this tool impractical for diagnosis in a medical emergency. Our product will bridge the gap between emergency and full hospital EEG.

Studies indicate that just two EEG channels, compared to the twenty-five commonly used in hospitals, is sufficient enough for several diagnostic purposes like epileptic seizure classification or predictions [2,3] . Our device uses four electrodes, which is sufficient for simple diagnoses when the need is urgent.

Traditionally, EEG electrode pads are applied to the scalp with a paste to improve contact and increase signal strength. Thanks to the recent effort and advanced technology of dry electrodes, it became possible to measure the EEG signal without the need to apply any conductive substance to the scalp, which complicates the process. [4] By switching to dry electrodes and bringing down the number of electrodes to 4, we managed to reduce the setup time to about one minute.

Instead of having a screen like the other EEG systems on the market, our device has a bluetooth module to transfer data to other smart devices for displaying data and signal processing. Patient EEG data can be instantly added to hospital network systems for physicians to access any time and anywhere. The collected data can be uploaded to cloud storage and may be used for machine learning-based diagnoses in the future.
