The glove that lets you "see" underwater

Researchers at the Tsukuba University in Japan have developed a sonar glove that allows swimmers or post-tsunami rescue teams to "see" with their fingers in murky waters.

Aisen Chacin and Takeshi Oozu created a very special DIY kit. IrukaTact is a portable underwater sonar system that, when used as a glove, will tell users they're approaching objects or other solid materials.

The PhD duo believes that their 3D-printed sonar can play a crucial role during flood searches. IrukaTact - a blend of the words "iruka" ( the Japanese word for "dolphin") and "tactile" - features small water jets that will help you feel and find anything up to two feet away.
