Study: Ears have tiny 'flexoelectric' motors to amplify sound Utah and Texas researchers have learned how quiet sounds are magnified by bundles of tiny, hair-like tubes atop "hair cells" in the ear: when the tubes dance back and forth, they act as "flexoelectric motors" that amplify sound mechanically."We are reporting discovery of a new nanoscale motor in the ear," says Richard Rabbitt, the study's principal author and a professor and chair of bioengineering at the University of Utah College...
