A new gearing aid has been designed that uses the teeth to pass signals to the ear. A hearing aid has been developed that uses the teeth to send signals to the inner ear for processing. The SoundBite is a new form of hearing aid that is surgical implanted into a person’s ear, Inhabitat reports. It is able to detect sounds and then uses a piezoelectric motor to send vibrations through the jaw to the teeth, where these vibrations are picked up by a sensor and then wirelessly sent to a receiver in the inner ear. Field tests have shown that patients reported 80 to 100 per cent hearing restoration when using the technology. The device is now undergoing Food and Drug Administration approval in the US and is likely to be available next summer with a price tag of $6,000 (£4,167). Elsewhere, a new tooth implant has been developed that is capable of holding a person’s entire dental history. The I-Denti-Fied chip is accessed using a scanner, which then sends the records to a computer so they can be read. It was designed and patented by dentist Kevin Brunski.
