提出了一种磁致伸缩材料与压电陶瓷复合的新型无线圈磁力控制器。磁力控制是基于磁致伸缩材料的逆磁致伸缩效应，由此通过致动器控制应变和磁力。由于压电作动器是电容式的，这种磁力控制方法具有稳态工作时零功耗的优点。此外，与传统装置相比，不需要鲁棒的约束结构的配置是简单的。研究了永磁体尺寸和预紧力对磁力的影响。
Novel composite of magnetostrictive material and piezoelectric actuator is proposed for coil-free magnetic force control. The magnetic force control is based on the inverse magnetostrictive effect of magnetostrictive materials whereby the strain hence magnetic force is controlled by the actuator. Because the piezoelectric actuator is an electrically capacitive, this magnetic force control method has the advantages of zero power consumption in steady-state operation. Furthermore, the configuration which requires no robust structure of constraint is simple compared with that of conventional device. The behaviour of the magnetic force dependant on the dimension of the permanent magnet and prestress is investigated.
