Exploration of High-Temperature Conduction Mechanisms in Disordered and Ordered Langasite-Type Piezoelectric Crystals

Huifen Yu, Hua Tan, Wu Fang, Ruonan Zhang et autres

Langasite-type crystals are widely used in high-temperature piezoelectric sensors owing to their excellent piezoelectric properties and outstanding stability. However, the decrease in resistivity at elevated temperatures can degrade the sensor performance. Understanding the electrical conduction behavior of these crystals is crucial for …

A High-Temperature Piezoelectric Accelerometer Operating in Symmetric Shear–Bending Coupling Mode

Wen Liu, Bin Wang, Shaotong Gong, Xiaoniu Tu et autres

(BS-PT) ceramic rings, operating in symmetric shear-bending coupling vibration mode is proposed. This coupling mode enhances effective electromechanical coupling through a charge amplification factor, yielding a high sensitivity (22.8 pC/g), approximately three times that of conventional shear-type accelerometers at room temperature. The …
