| 摘 要： | 研究了可用于磁场传感器的磁电复合材料, 对传统的磁电复合材料进行了结构创新, 采用条状PZT和 Terfenol-D 的材料体系, 用热固树脂进行粘合, Terfenol-D 沿长度方向磁化且PZT条沿厚度方向极化。与传统的1-3型复合不同的是: 每根PZT的输出极被串联起来。在同样的磁场激励下, 新型复合材料的输出电压为相同体积的同种结构复合材料的2.2倍, 增强了材料对磁场的灵敏度和抗噪声性能。

| Abstract: | A novel magnetoelectric(ME) composite which is suitable for magnetic sensor was fabricated,its structure is different from conventional ME composites.The strip PZT(Pb(ZrTi)O3) and Terfenol-D were laminated bonded with the thermoset epoxy.Terfenol-D layer was magnetized in its longitudinal direction and piezoelectric PZT strips were polled in their transverse direction.Every PZT strip was electrical series connected together,different from conventional 1-3 type ME composite.It gets much larger voltage output... |
