Shape memory alloy (SMA) is an intermetallic compound able to recover, in a predetermined shape during a thermal cycle while generating mechanical work. The primary objective of this research is to develop a shape memory alloy based micro-positioning stage. This paper reports about the training, actuation method of NiTi shape Memory alloy thin sheets and its displacement measurement through Michelson Interferometer. The SMA based Tripod was fabricated the actuation was done using an electrical biasing with 5 A(1.2 Volt) where a displacement of around 6.10 mm was achieved. The actuation studies were also performed using a laser with a optimum fluence of 100 mJ/cm2that is of upto7.25 mm achieved.

As a result of diverse elements like outdated learning methodology and imbalance of theoretical and experimental knowledge, over 75% of engineering graduates in India are not readily employable. They do not possess real-world skills needed by the corporations. This research discusses strategies for a combined approach of project based learning (PBL) and student social responsibility (SSR) to reinforce real-world skills among undergraduate students. A comprehensive case study carried out by IEEE Madras Section Special Interest Group on Humanitarian Technology (SIGHT) on students from multiple institutions based on these strategies have been illustrated in this paper. Furthermore, the outcomes of the case study relating to student proficiency development and its social implications are presented.
