Explanation:-- Mechanical engineering products and systems that employ some form of electrical engineering principles and devices have been developed and used since the early part of the 20th century. These systems included the automobile, electric typewriter, aircraft, and elevator. Some of the power sources used in these systems were not necessarily electrical, but there were batteries and/or the conversion of thermal power into electricity through generators. These electromechanical systems were not Mechatronics systems because they did not use an integrated approach characterizing Mechatronics for their analysis, design, development, and implementation Rapid advances in electromechanical devices and systems were possible particularly due to developments in control engineering, which began for the most part in the early 1950s, and still more rapid advances in digital computer and communication as a result of integrated circuit (IC) and microprocessor technologies, starting from the late 1960s. With these advances, engineers and scientists felt the need for an integrated multidisciplinary approach to design and hence a mechatronic approach. Yasakawa Electric in Japan was the first to coin the term mechatronics, for which the company obtained a trademark in 1972. With today’s sophisticated technologies of mechanics and materials, analog and digital electronics, sensors, actuators, controllers, electromechanical design, and micro-electromechanical systems (MEMS) with embedded sensors, actuators, and microcontrollers, the field of mechatronics has attained a good degree of maturity. Now, many universities around the world offer undergraduate and graduate programs in mechatronic engineering, which have become highly effective and popular among students, instructors, employees, and employers
