Fish-Inspired Sensor "Touches" Using Electric Fields

The ability to detect a nearby presence without seeing or touching it may sound fantastical—but it’s a real ability that some creatures have. A family of African fish known as Mormyrids are weakly electric, and have special organs that can locate a nearby prey, whether it’s in murky water or even hiding in the mud. Now scientists have created an artificial sensor system inspired by nature’s original design. The development could find use one day in robotics and smart pros
