项目摘要

Technical importance of multi-ferroic approach for designing advanced multi-functional actuator/sensors based on a mutual coupling effect between ferroic material elements is pointed out for intelligent/smart technology. Two types of multi-ferroic actuator/sensor devices. i.e. (1) magnetically driven composite actuator and (2) multi-functional surface acoustic wave (SAW) sensor by MEMS are presented. First, a large-scale robust composite actuator is the composite structure which is reinforced by the superelastic fiber or lamellar of shape memory alloys (TiNi) in the ferromagnetic metal (Ni) matrix. This multi-ferroic composite can be driven with high speed as well as considerably enhanced strain by applying a wireless magnetic field. Secondarily, multi-functionally designed, multi-ferroic senor device using surface acoustic wave (SAW) is introduced. On the surface part between IDTs, environmentally active material films such as SMA, FSMA, magnetostrictive alloy etc. are formed by magnetron-sputtering. Various environmental sensing parameters i.e. temperature, magnetic field strength, stress, loading hysteresis and internal damage etc. can be evaluated nondestructively from the signal analysis of amplitude and phase change of SAW. Consequently, these results show the promising new types of multi-functional composite actuator and sensor based on multi-ferroic effect.

指出了多铁性方法对于设计基于铁性材料元件间相互耦合效应的先进多功能致动器/传感器的技术重要性。两种类型的多铁致动器/传感器装置。提出了(1)磁驱动复合驱动器和(2)基于MEMS的多功能表面声波传感器。首先，在铁磁金属（Ni）基体中加入超弹性纤维或形状记忆合金（TiNi）片层进行增强的复合材料结构是大型鲁棒复合驱动器。这种多铁复合材料可以高速驱动，并通过施加无线磁场大大增强应变。其次，介绍了一种基于声表面波的多功能多铁传感器。在idt之间的表面部分，通过磁控溅射形成SMA、FSMA、磁致伸缩合金等环保活性材料薄膜。通过对声表面波振幅和相位变化的信号分析，可以对温度、磁场强度、应力、载荷滞后和内部损伤等各种环境传感参数进行无损评估。因此，这些结果显示了基于多铁性效应的新型多功能复合致动器和传感器的发展前景。
