Current alternative for hearing impaired the cochlear implants are expensive and requires surgery where as Vibrotactile Extra-Sensory Transducer or “Vest” can be wear o your torso and it will translate sound into tactile feedback. With training the brain can learn to translate Vest’s vibration in to data.
The concept of Vest is same as Cochlear implants but it will not require surgery. Our brain can’t hear, it just interprets electrical signals and present to your consciousness as perception. If our body can interpret electrical signals from the ear as sound or data then in the same manner sound based electrical signals can originate from the surface of skin.
