Vibrotactile Extra-Sensory Transducer (VEST)

Neuroscientist Dr. David Eagleman from Baylor College of Medicine in Texas has probably found a cure for millions of people with hearing loss by designing a unique wearable vest. Vest allows people to ‘feel’ the sounds around them through their skin. They can hear through their sense of touch. The machine would communicate the sound as vibrations on the skin which will be interpreted by the brain as sound.
There are about 360 million people with hearing impairments worldwide and about 63 million in India. The device works on the concept of sensory substitution – finding alternative ways for one sense to be experienced by another.
The device, designed as a wearable vest, also uses a Smartphone to absorb and process external sounds into data. The phone then transfers the information using blue tooth technology to vibration motors on the vest, which transfer it to the brain in the form of electrical signals, thereby replacing hearing with touch-based senses
