Mr. Hall and his team used the chemical element silicon to copy the flys ear structure. They also used special electric materials that enable them to measure its movements at the same time.
Hall says the hearing aid device could be used in two ways. One way would be to help the military on the battle field, there, sensors could find where shots are coming from. The second way would be to remove unwanted noise from a persons surroundings.
That is a feature that is incredibly useful for hearing aids, for example, where right now, if you turn up the gain of a hearing aid or turn up the volume to hear someone across from you, it also amplifies everything else in the room, said Hall.
Hall says the next test in marketing the hearing aid device is to make it usable. He says the device must be handled carefully because it is so small. He notes that the fly does not have this concern.
