Middle-Ear Microphone Implanted in Cadaver

Caption: A new kind of tiny microphone is shown here attached at right to a cadaver’s umbo, where the eardrum (under left part of device) meets the hearing bones. The microphone includes an accelerometer and silicon chip that detect vibrations and convert them to electronic signals sent to electrodes in the inner ear’s cochlea, and from there to the brain. The device measures about one-tenth inch by one-quarter inch.
