    摘要: The present invention relates to methods for the batch fixation and electrical connection of pre-strained SMA wires on a microstructured substrate using electroplating, providing high bond strength and electrical connections in one processing step. The integration process here developed relies on conventional micro machining techniques and it provides an efficient solution to some problems that have hindered the widespread diffusion of bulk SMA to MEMS, such as the lack of cost-efficient integration methods of bulk SMA and the difficult electrical contacting of the actuator material at small scale. Also disclosed herein is a Joule-heated SMA wire actuator on silicon MEMS.
