This paper presents the design and fabrication process of a PMUT array with adaptive directivity in order to study the beam pattern and acoustic power intensity of PMUT arrays. The proposed PMUT array consists of four 6 × 6, 8 × 8, 12×12, and a directional 6×6 arrays. Each array can be actuated separately. A detailed mathematical study, which is followed by FEM simulation, on directivity , beam pattern, and the acoustic power intensity is discussed. The fabricated array has resonance frequency
