EpiCare@Home Validation Study for Focal Onset Seizures

Inclusion Criteria: * Adult (age ≥ 18) and adolescent (12 ≤ age \< 18) patients with a known history or suspicion of focal onset epilepsy, including focal-to-bilateral tonic-clonic seizures * A clinical indication for ≥ 1 h EMU observation. * Participants should be able to maintain a seizure diary in the provided EpiCare@Home Patient App (themselves or via a caregiver). Alternatively, the use of a paper seizure diary is allowed. Exclusion Criteria: * Inability to provide written informed consent, either direct or via a proxy. * Known allergy or skin-sensitivity to the materials used in the Byteflies Adhesives or any 3rd party biopotential electrode. * Having an implanted device may be grounds for exclusion, depending on the type and location of the implant. Implanted devices, such as (but not limited to) pacemakers, cardioverter defibrillators (ICD), and/or neural stimulation devices may contain magnetic switches. Byteflies Sensor Dots contain magnets that may interfere with the operation of these devices. The chance of this happening based on the strength of the magnets is exceedingly low (for comparison, the magnet strength is 10x lower than what is found in Apple Magsafe cases) but it has not been excluded by formal testing either. The risk will be evaluated on a case-by-case basis. * Any other condition or finding that would compromise the safety of the participant or the quality of the study data, or otherwise interfere with achieving the study objectives, as determin…
