  THE EVOLUTION OF ELECTRIC VEHICLES (EVs) 1. Introduction Transportation plays a crucial role in modern society, but conventional internal combustion engine (ICE) vehicles contribute significantly to air pollution, greenhouse gas emissions, and depletion of fossil fuels. Electric Vehicles (EVs) have emerged as a sustainable and energy-efficient alternative. Electric vehicles use electric motors powered by batteries or other energy storage devices instead of gasoline or diesel engines. Though EVs are often considered a modern innovation, their history dates back to the 19th century. This seminar discusses the historical development, technological evolution, types, components, advantages, challenges, and future scope of EVs . 2. Early History of Electric Vehicles (1830–1900) The first experimental electric vehicles were developed in the 1830s . In 1834 , Thomas Davenport (USA) built a small electric-powered vehicle. In 1888 , Andreas Flocken (G...

Metrology in Medical Devices Metrology plays a crucial role in ensuring precision for medical devices, directly relevant to mechanical engineering students studying manufacturing and quality control. This blog content introduces key concepts, tools, and applications tailored for your curriculum. What is Metrology? Metrology is the science of measurement, focusing on accuracy, traceability, and repeatability in manufacturing. In medical devices, it verifies dimensions, surfaces, and tolerances to meet standards like ISO 13485 and FDA guidelines, preventing failures that could harm patients. For mechanical engineering students, it bridges design principles with production, using tools like calipers, micrometers, and advanced systems. Importance in Medical Devices Medical devices such as implants, surgical tools, and prosthetics demand sub-micron precision due to biocompatibility and functionality needs. Even small deviations can cause malfunctions, so metrology ensures compliance during ...
