Virtual Reality (VR) and Augmented Reality (AR) have revolutionized technology and taken the world by storm. They established the foundation for numerous future innovations. Virtual and augmented reality are now widely employed to improve user experiences in various areas. Over time, more and more companies and businesses have begun to use this cutting-edge technology to improve their products and services. Recently, the attention to VR and AR has exploded with the concept “Metaverse” surfacing in mainstream media. Many major companies have already set their goals in motion and are working on building the core of their metaverses. This review paper focuses on explaining the concept of the metaverse, its history, and its associated benefits. Through a survey, it helps understand people’s concerns with the metaverse and how it can impact and affect humans mentally, physically, and psychologically. The analysis of this paper can help humans prepare themselves for what the new technologies have to offer, in addition to assisting companies in building a flawless metaverse.

This current work focuses on the study of residual stress introduced in thin surface micromachined films due to the thermal stress. A model is presented here to study the change in thermal residual stress as the temperature changes and in turn how this change affects the resonant frequency of the resonator. The model uses two design; a resonator with straight and folded cantilevers. This work also involves in analysing the resonator performance as the material properties are changed. The analyses is done on Nitinol which is a Shape Memory Alloy (SMA). The simulation is carried out on COMSOL Multiphysics.
