heat-sensing film
Invisible 'snake skin' could let robots sense humans
Scientists have pulled inspiration from snakes to help robots detect when humans are near. The heat-sensing film has the ability to detect tiny temperature changes, and was inspired in the sensors a viper uses its skin to find prey. Researchers foresee this technology being used by search and rescue robots in order to locate humans in disaster zones. Scientists have pulled inspiration from snakes to help robots detect when humans are near. The heat-sensing film is a flexible, transparent coating made of pectin.
