How can what engineers learn from how barn owls pinpoint the location of the faintest sounds apply to their development of nanotechnologies capable of doing even better? In episode 61, we're joined by Saptarshi Das, a nano-engineer from Penn State University, who talks with us about his article "A biomimetic 2D transistor for audiomorphic computing," co-authored with Sarbashis Das and Akhil Dodda, and published on August 1, 2019 in the open-access journal Nature Communications.
