Presently engineering science plays a critical part in the environmental monitoring and healthcare. Through this research effort an array of micro cantilever is designed and analyzed with the help of Micro-Electro-Mechanical -Systems (MEMS) technology. Aim of this study is device should be easy to design, consume less energy, be simple to model, and be cost-effective and efficient. As a result, micro cantilevers are the perfect platform to explore for such issues because they can be employed as a very sensitive element in a variety of applications and different environment. Instead of a micro cantilever, a micro cantilever array has been modeled to improve the sensitivity. Because the device's output should be high, several types of studies have been carried out, including the use of nine unlike materials and accordingly the improvement in the sensitivity, as a conclusion SiO2 is the best choices for maximum displacement. Aside from that, several geometrical shapes built and analyzed for improved sensitivity in the form of maximum displacement. During the analysis process, a few facts emerged, such as how to make micro cantilever arrays simple and cost-effective. Instead of utilising three micro cantilevers as arrays, two micro cantilevers with the same efficiency can be utilized by adjusting the forces on the arrays' surfaces. Improved sensitivity and utmost displacement can be achieved by reducing effective areas across fixed end utilizing different geometrical variations. This inquiry report could be relevant in the development of a micro cantilever biosensor for the detection of various diseases. © 2022 Elsevier B.V., All rights reserved.
