Ultrasonic Transducers Made From Freeze-Cast Porous Piezoceramics [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2022 Porous and composite piezoelectric ceramics are of interest for underwater ultrasonic transducers due to their improved voltage sensitivity and acoustic matching with water, compared with their dense counterparts. Commonly, these materials are fabricated by dice-and-fill of sintered blocks of polycrystalline piezoceramic, which results in a high volume
