------PROTOTYPE-----Words in the mouth: CSU device allows user to hear with their tongue. Researchers at Colorado State University (CSU) are developing a hearing device that bypasses the ear and puts words in the mouth. The technology relies on a Bluetooth-enabled earpiece to detect sound and send electrical impulses to an electrode-packed retainer that wearers press their tongue against to “hear".

Technical Specifications: 

Unlike hearing aids, which amplify sound, cochlear implants circumvent damaged areas of the ear and stimulate the auditory nerve directly. Microphones outside the ear detect sounds and send them to a speech processor, which analyzes the information and transmits it to a receiver where it is converted into electric impulses. The implant sends those impulses directly to the auditory nerve. With training, the brain learns to recognize these impulses as useful sound information. The CSU device operates similarly, except electric impulses are sent via Bluetooth to a retainer-like mouthpiece packed with electrodes. When users press their tongue against the device, they feel a distinct pattern of electric impulses as a tingling or vibrating sensation.
