Elasmobranch fishes, such as sharks, skates and rays, use a network of electroreceptors distributed on their skin to locate nearby prey. The receptors can detect the electric field generated by the biomechanical activity of their prey. By comparing the intensity of the electric fields sensed by each receptor in the network, the animals can estimate the relative positions of nearby prey without making physical contact. Inspired by this capacity for prey localization, we developed a soft artificial electroreceptor that can detect the relative positions of nearby objects in a non-contact manner by sensing the electric fields that originate from the objects. By wearing the artificial receptor, a person can receive spatial information of a nearby object in real time via auditory signals. The soft artificial electroreceptor is expected to expand the ways in which a person can perceive space by providing a new sensory modality that did not evolve naturally in human beings. |
