Research

Optalert is committed to the research and development of drowsy driver assistance technologies. Our goal is to become the leading global provider of such technologies to meet the demands of road, rail, mining, defence and other transport industries world-wide.

Dr. Murray Johns is a world authority on sleep medicine and related technologies. He has assembled a world-class team of researchers to ensure Optalert remains at the forefront of drowsiness monitoring technologies.

Results of Optalert research and product validation has been widely published by both the Optalert research team and leading research institutes around the world.
