Types of seizure detection systems for at-home monitoring of epilepsy.

Detection system	Description	What it monitors
Wearable sensors [9]	Wearable device (such as a watch or other wrist-worn sensor)	Primarily movement and heart rate, some can also measure other skin properties (temperature, sweat, etc)
Apps/subscriptions [9]	Mobile app, usually linked with a wearable sensor	Can send alerts to people about a seizure, track location via GPS, track seizures, send medication reminders, etc
Bed monitors [9]	Sensors placed under a mattress, linked with a pager	Primarily movement and sound, some can also monitor vomit and urination
Video monitors [9,13]	Infrared camera device, linked with app, pager, or other monitoring tool	Primarily movement, but can also record audio and other visible signs
Ambulatory scalp electroencephalography [14-17]	Electrodes/sensors attached to scalp	Electrical brain activity
Subcutaneous electroencephalography [18,19]	Electrode implanted under skin, attached to small logging device	Electrical brain activity
Intracranial electroencephalography [20]	Electrode implanted in the brain, attached to small logging device	Electrical brain activity
