Abstract

(1–0)–3 single-crystal piezocomposite (SCPC) based on [011]-oriented relaxor PIN-PMN-PT crystal was fabricated via a modified method combining 3D printing-assisted dice-and-insert with dice-and-fill techniques. The (1–0)–3 SCPC, characterized by ordered and poled microholes and incorporating a dual-piezo-charge mechanism, achieves an ultrahigh hydrostatic figure of merit d_hg_h of about 8089 × 10⁻¹⁵ m² N⁻¹. The ultrasound transducer based on (1–0)–3 SCPC exhibits a ~ 70% enhancement in underwater acoustic sensitivity while maintaining a broad − 3 dB bandwidth of 130 kHz.
