Ultrasonic transceiver arrangement having increased ultrasonic signal reception

A transceiver apparatus for maximizing voltage, comprising:

• a substrate having a first surface and an opposing second surface;
• a first layer of a plurality of piezoelectric transducers attached to the first surface of the substrate;
• a buffer layer attached to the first layer of the plurality of piezoelectric transducers;
• a second layer of one or more piezoelectric transducers attached to the buffer layer such that the buffer layer is between the first and second layers of the plurality of piezoelectric transducers;
• and
• wherein at least one of the first layer of the plurality of piezoelectric transducers and the second layer of the plurality of piezoelectric transducers are connected in series in a cascaded configuration via electrical connectors,
• wherein the other of the first layer of the plurality of piezoelectric transducers and the second layer of the plurality of piezoelectric transducers are confirmed to emit an ultrasonic wave toward the substrate, and
• wherein the at least one of the first layer of the plurality of piezoelectric transducers and the second layer of the plurality of piezoelectric transducers that is connected in series in the cascaded configuration is positioned at a focal point of a diffraction pattern of the ultrasonic wave in the substrate.
