0303536TayaAn SGER award supports research on the design of mechanically active surfaces using ferromagnetic shape memory alloys. The FePd alloy can be made to switch surface morphology between flat, corresponding to the austenite phase and the magnetic field turned off, and sawtooth form, corresponding to the martensite phase and the magnetic field turned on. The morphology change may potentially be useful in design of brakes or propulsion systems for miniature systems. The work will entail development of suitable single crystal plates with optimal martensite twin morphology, testing for durability and speed of switching, and initial tryouts in miniature mechanisms.The broader impact of the work is that it could result in development of a new method for providing miniature movement, or braking for a large number of industrially important MEMS and other miniature systems and devices.***

0303536TayaAn SGER奖支持使用铁磁形状记忆合金设计机械活性表面的研究。 FePd合金可以在平面（对应于奥氏体相且磁场关闭）和平面（对应于马氏体相且磁场打开）之间切换表面形态。 这项工作将包括开发具有最佳马氏体孪晶形态的合适单晶片，测试耐久性和切换速度，并初步试用微型机构。这项工作的更广泛影响是，它可能导致开发一种新方法，为大量工业上重要的MEMS和其他微型系统和设备提供微型运动或制动。*
