"American ecologist and hearing specialist Caitlin O'Connell-Rodwell is developing a new hearing aid inspired by elephants. Along with sound, elephants pick up ground-based vibrations, as the skin of their feet and trunks contains mechanoreceptors that can sense them. [...] She has partnered with HNU Photonics, a research company based on Maui, Hawaii, to develop a patch that adheres to the skin; this transduces sound into vibrations, which the braininterprets as a kind of Braille or Morse code."
