Development of Bone Conduction Hearing Device using Nano Direct Current Drive

This paper discusses about the development of new bone conduction hearing device using micro drive. The aim of this work is to help the people with hearing disability by developing a simple device with less cost. Technological development should be helpful to the needy. Bone conduction technology is used here to transmit sound from outside world to cochlea through teeth but without any surgery. The sound wave is converted into vibration by microphone and micro drive set up, when the micro drive is placed between teeth the signal is transferred from the teeth through the skull bones and into the cochlea. Thus the deaf people can hear the voice. The available bone conduction hearing devices are having disadvantages like surgery, cost and electrode metal inside the body etc., the proposed work is an attempt to overcome these problems. The device was tested in the laboratory and the converted electrical output signal is viewed with the help of oscilloscope.
