<p>This thesis has developed a microelectromechanical directional acoustic sensor based on directional finding capabilities that the Ormia Ochracea fly uses. Previous versions of this sensor have been characterized in the air to exploit resonance modes and resolve bearing ambiguity of an incident sound wave. New sensors have been designed and fabricated for use in the underwater environment. This thesis focuses on the development of these underwater sensors. The research involved design, simulation and experimental characterization of these sensors in both air and water. The sensors show readiness for further development and that they can be vital as a directional finding sound sensor in numerous undersea applications.
