Rescue workers searching flood sites have a unique challenge – they need to know what's under the water, but invariably that water is going to be very murky. Well, that's the main scenario for which the IrukaTact was created. It's a submersible haptic feedback glove that lets users "feel" what's below the surface, without having to dive down to actually touch it.
While just about everyone knows that bats locate prey in the dark using echolocation, one thing that many people may not
realize is the fact that horseshoe bats are particularly good at it.
With this in mind, engineers at Virginia Tech are now developing a sonar
system that emulates the system used by those bats. Once perfected, it
could be a much more compact and efficient alternative to traditional
manmade sonar arrays.
