Rolf Mueller, professor of mechanical engineering at Virginia Tech, has drawn inspiration from bats to design and develop a new bio-inspired technology that can determine the origin location of a sound. Unlike previous approaches, which are often based on the human ear, Mueller looked at a bat’s ear to gain the first new insight into identifying sound location in 50 years. “I have long admired bats for their uncanny ability to navigate complex natural environments based on ultrasound and suspected that the unusual mobility of the animal’s ears might have something to do with this,” he said. Mueller was joined by former Ph.D student and lead author Xiaoyan Yin. The findings were published in Nature Machine Intelligence
