There's money here to whoever can capture the activation of these muscles to control prosthetic cat ears. At the rate I see them the prosthetic cat ear market must be double-digit billions. Seriously, though, it makes me wonder if the activation of these muscles could be used in a hearing aid application. Why not add a couple rear-facing highly directional mics and use these muscles to control their gain?
