Abstract
Electrochemical micromachining (ECMM) with ultrashort voltage pulses has been used to fabricate microstructures on a NiTi shape memory alloy (SMA). Because of its unique properties, NiTi is a desirable material for use in various applications including medical devices and actuators. ECMM is a heat free, strain free, and mask free method for microfabrication, and therefore well suited for use with shape memory alloys . Microstructures were machined to a depth of 3 μm on NiTi surfaces, and the lateral resolution of the machining was found to be dependent on the duration of the voltage pulses used.
