Nowadays, piezoceramics are commonly used in ultrasonic transducers (underwater applications, medical imaging, NDT …). Most of them are PZT-based materials (Pb(Zr, Ti)O3), which causes environmental issues due to the presence of lead. To comply wit

Barium titanate (BaTiO3) is a well-known ferroelectric material which was intensively studied in the early 50's. Indeed, BaTiO3 has been rapidly substituted by lead zirconate titanate (PZT) materials, which exhibit higher piezoelectric properties. Ho

The standard fabrication method for 1–3 piezocomposites for ultrasound transducers is the “dice and fill” method (DFM) in which lateral periodicity is introduced. This contributes to the appearance of spurious modes that can drastically affect
