With state-of-the-art advances in technologies, many developments have been reported in the field of materials. Discussion on graphene being seen as a potential and better substitute of silicon has been there in scientific literature. The objective of this course is to introduce some of such materials and their properties to the students. This exposure would help them use and handle these materials in their professional career. Engineered materials may also be called smart materials. These are materials which show strong couplings between the applied stimuli such as electrical, magnetic, optical or thermal field with their mechanical properties, viz., eleasticity, viscocity etc.. Such couplings provide built-in mechanisms for sensing and actuation. There is wide range of smart materials such as piezoelectrics, ferromagnetic alloys, shape memory alloys, electroactive polymers, spintronics, etc. Due to their compact sizes and unique properties, smart material sensors and actuators have broad applications in robotics, aerospace industry, biomedical devices, automotive systems, and many more. In particular, they provide promising solutions in emerging areas such as biomanipulation, prosthetics, implantable drug delivery systems, wearable devices, and scanning probe microscopy.
The goal of this course is to expose the students to the general area of some of these materials with an emphasis on novel materials and emerging applications. Students will learn the potentials of these materials as sensing materials and/or semiconductor/conductor materials, their potential use in new devices, the challenges associated with their uses, and the approaches to address these challenges.This is an introductory level course. It does not deal with the fabrication techniques of these novel materials. Also this course is not a material science course.
