Abstract :

              Bulk shape-memory-alloy actuators have great potential to be used in various microdevices. Previous studies show that this material is very attractive due to its very large force, high mechanical robustness with a simple structure and biocompatibility. This proposal presents a novel shape memory alloy micromanipulator through applying an integration of multiple shape memory alloy microactuators. Moreover, the micromanipulator will be developed using monolithic approach. Due to the challenges exist in developing the integration and the monolithic approaches into micro-electro-mechanical systems (MEMS) fabrication, the success of bulk shape memory alloy in MEMS is rather limited today. The successful outcomes of this research are expected to promote advances in these device technologies in biomedical fields and beyond. This report discusses the important measures that are necessary to develop the shape memory alloy micromanipulator, and then reviews on the challenges and status of current strategies.
