NightWatch Epilepsy seizure detection system


Safe and effective seizure detection system

NightWatch is a comfortable armband that closely monitors the wearer’s heart rate and motion during sleep.


When the system suspects a possible major epileptic seizure, a warning is transmitted to a caregiver via a wireless signal to the armband’s corresponding base station.


The system is optimized to detect all possible dangerous epileptic seizures, including tonic and tonic-clonic seizures.

User experiences

“NightWatch is a system that was developed in collaboration with patients and which reliably recognizes nocturnal motor seizures and raises the alarm. A long-cherished wish of many, enabling them to sleep more peacefully.”

Dr. F.S.S. Leijten


UMC Utrecht

“We feel completely reassured thanks to NightWatch. We are always alerted if our daughter Leen has a severe seizure. When Leen stays over somewhere, the device goes with her so that the night-time care team will be alerted in the event of a seizure.”

K. Blomme-Dorme

Father of Leen

“NightWatch detects seizures far more effectively than the product we used previously and is, therefore, part of our medical kit.”
