Epilepsy and safer sleeping

The NightWatch is a clinically proven system for detecting dangerous epileptic seizures during sleep.

The NightWatch

Safe and effective seizure detection system

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

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

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


You can now try the NightWatch for one month, no strings attached.

User experiences

“The NightWatch is a system that was developed in collaboration with patients and which reliably recognises 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 the NightWatch. We are always alerted if our daughter Leen has a severe seizure. When Leen stays over somewhere, the NightWatch 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

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

A. van Hest

Complex Care Team Leader


Our story

The NightWatch system and our company, LivAssured, as a whole came about as the result of a unique partnership between the Kempenhaeghe and SEIN epilepsy centres, the University Medical Centre (UMC) Utrecht, Eindhoven University of Technology, the Epilepsiefonds (Epilepsy Foundation), and patient representatives.

The LivAssured team consists of experienced entrepreneurs and motivated engineers with a passion for making innovative medical technology accessible to those who really need it to be able to live life as normally as possible.
