These sensors usually involve biological molecules such as antibodies or enzymes, which interact with analyses that are to be detected. Advancements in Mechatronics  Avionics:  Numerous and complex mechatronic systems are used in advanced commercial and military aircrafts. With the ever- increasing emphasis on robustness and safety, there is a trend towards using more mechatronic systems in aerospace industry.  The major applications of mechatronic systems in aerospace industry can be classified as follows:  Cockpit instrumentation ( flight deck)  Safety devices  Wind tunnel instrumentation  Sensors for fuel efficiency and safety  Microgyroscope (IMU) for navigation and stability  Microsatellites  Mechatronics Products FAX Ibot Robotic Wheelchair Slot DVD Drive Photocopy machine Mechatronics Products Autotronics Mechatronics Products Bebionic Hand Prosthetic Knee  Mechatronics Products Modern Trends of MS Development Avionics  Aviation, space and military techniques;  Mechatronic System Design  The mechatronic design methodology is based on a concurrent (instead of sequential) approach to discipline design, resulting in products with more synergy.  The branch of engineering called systems engineering uses a concurrent approach for preliminary design. In a way, mechatronics is an extension of the system engineering approach, but it is supplemented with information systems to guide the design and is applied at all stages of design (not just the preliminary design step).  Mechatronics is a synergy in the integration of mechanical, electrical, and computer systems with information systems for the design and manufacture of products and processes. The synergy is generated by the right combination of parameters; the final product can be better than just the sum of its parts.  Mechatronic products exhibit performance characteristics that were previously difficult to achieve without the synergistic combination.  Mechatronic System Design  Mechatronic system design supports the concepts of concurrent engineering.  In the designing of a mechatronic product, it is necessary that the knowledge and necessary information be coordinated amongst different expert groups.  Concurrent engineering is a design approach in which the design and manufacture of a product are merged in a special way. It is the idea that people can do a better job if they cooperate to achieve a common goal. It has been influenced partly by the recognition that many of the high costs in manufacturing are decided at the product design stage itself.  Mechatronic System Design  The characteristics of concurrent engineering are:  Better definition of the product without late changes.  Design for manufacturing and assembly undertaken in the early design stage.  Process on how the product development is well defined.  Better cost estimates.  Decrease in the barriers between design and manufacturing.  However, the lack of a common interface language has made the information exchange in concurrent engineering difficult.  Successful implementation of concurrent engineering is possible by coordinating an adequate exchange of information and dealing with organizational barriers to cross-functional cooperation.  Using concurrent engineering principles as a guide, the designed product is likely to meet the basic requirements (High quality, Robustness, Low cost, Time to market, and Customer satisfaction) Industry Revolution and Automation Inspired Design by Nature Questions ?? 33
