Sensor gloves detect obstacles for firefighters in smoky rooms

University of Minnesota researchers have taken a step toward providing first responders with a new means of finding their way through dark or smoky buildings.

Lucy Dunne, an assistant professor in the College of Design’s Department of Design, Housing & Apparel, and graduate student Tony Carton, working with funding from the U’s Minnesota Agricultural Experiment Station to augment the sensory awareness of first responders like firefighters, designed gloves that use ultrasonic sensors to detect walls and other objects.
