Abstract: The present invention is directed to an acoustic vector sensor (200), specifically an underwater acoustic vector sensor. The acoustic vector sensor (200) contains three piezoelectric sensors (210) orthogonally mounted inside a rigid housing (302), where each of the piezoelectric sensors measures acoustic energy from one of the three different, orthogonal, axial directions (X, Y, and Z). The piezoelectric sensor contains a proof mass (202), a base (206), and a piezoelectric crystal sandwiched there between. The bonding surfaces of the proof mass and the base are preferably castellated; and the piezoelectric crystal is preferably a shear mode (d15) relaxor single crystal.
