Boosting Piezoelectric Voltage Constant in 3D‐Interconnected PZNNT Porous Piezoceramics via Pore Architecture Engineering

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT In conventional piezoceramics, the coordinated change between the dielectric constant (εr) and the piezoelectric charge constant (d33) usually limits the piezoelectric voltage constant g33 (g33 = d33/εr), a critical figure of merit for piezoelectric sensors.

Excellent Comprehensive Electromechanical Properties in PZT‐Based Hard High‐Temperature Piezoceramics

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

The Use of Phononic Crystals to Design Piezoelectric Power Transducers

Sensors, 2017
It was recently proposed that the lateral resonances around the working resonance band of ultrasonic piezoelectric sandwich transducers can be stopped by a periodic array of circular holes drilled along the main propagation direction (a phononic crystal).

Providing of Rod Piezoceramic Electroacoustic Transducers Thermal Mode Operation [PDF]

Microsystems, Electronics and Acoustics, 2019
The basis of the electro-acoustic transducer is piezoceramics - a quite fragile material. A rod type transducer was chosen for analysis due to the lack of research on this type of transducer and its widespread use. The most dangerous operational load is thermal.

Inferring cumulative crack widths in reinforced concrete structures using Coda Wave Interferometry of ultrasound

Structural Concrete, Volume 27, Issue 1, Page 247-262, February 2026.
Abstract Whether concrete structures are cracked, how wide these cracks are, and whether they must be regarded as damaging, is a central issue in structural health monitoring. Ultrasonic measurements evaluated with the sensitive Coda Wave Interferometry (CWI) have the potential to detect cracks early—long before they become visible. This paper presents
