Microtechnology engineering is the design, manufacture or use of very small, series-produced parts, apparatus and systems. It is behind a large number of products and the technologies required to make them. A great many domains directly or indirectly benefit from advances in microtechnology engineering. As well as the more traditional applications such as watchmaking and precision mechanics, the medical profession and electronics increasingly benefit from the possibilities opened up by miniaturisation and nanometric scale. A microtechnology engineer works in areas that overlap mechanics, electronics, materials science and IT, and must have a complete understanding of the physical laws involved in miniaturisation processes.
