A multilayer ultrasonic transducer includes a multilayer piezoelectric substrate assembly (100) laminated with a first and a second piezoelectric substrate on top of each other, and having a first electrode node (42) and a second electrode (44) node polarized with a primary electrode and a secondary electrode, respectively, a flexible printed circuit board coupled to the first electrode node, a backing block with a predetermined thickness surrounded by the flexible printed circuit board, a ground flexible printed circuit board coupled to the second electrode node, and an acoustic matching layer deposited on the multilayer piezoelectric substrate assembly.
