Abstract: A method for fabricating a vibrational transducer comprises providing a base structure, typically a material suitable for microfabrication. A cantilever beam is formed on a surface of the base structure, and is patterned into a desired geometry. The cantilever beam will be anchored at one end to the base structure and will have a free end which is capable of vibrating relative to the base structure. An inertial mass is formed at the free end of the cantilever beam, and the inertial mass is disposed to vibrate in a free space. An electrically conductive element is formed on the cantilever beam in he space between the anchored end and the free end. A fixed electrically conductive drive element is also formed on or over the base structure, adjacent to and spaced-apart from the electrically conductive element. A housing is formed over the base structure to seal the transducer so that it is suitable for implantation or other uses.
