Smart Mouthware was designed by Sapien LLC to assist deaf and hard of hearing individuals. Learn more. The device converts sound into electrical impulses to be sensed on the user's tongue. Through sensory substitution, the brain, in theory, will learn to interpret these impulses as sound. The current data transfer method consumes excessive amounts of power and a battery must reside orally. This project aims to create an efficient wireless power and data body area network.
