Engineering aims to generate technology in the form of products and services by implementing scientific knowledge. The Department of Mechanical and Manufacturing Engineering focuses much of its research and education resources in the areas of microtechnology and nanotechnology.
Microtechology is concerned with the implementation of miniaturization science and techniques in order to fabricate, analyse and characterise products with features at the micron scale. Even though the typical product in microtechnology is the electronic chip, miniaturized electronic components on a common silicon substrate, other mechanical components have also been miniaturized such as for example the micro-accelerometers for automobile airbags, micro-diaphragms for pressure sensors, micromirrors for fibre optics and microcantilevers for biosensors. The integration of such mechanical components with associated electronic components creates the Micro-Electro-Mechanical Systems, MEMS.
Nanotechnology studies the physical, chemical, electrical and mechanical properties of human engineered and physical structures that possess features at the nm scale, namely from 1nm to 1μm. This technology is highly motivated by the biological structures of nanometre scale found in animal and plant cells. Humans endeavour to integrate properties such as replication and its regulation by DNA and RNA, light sensing by rods and cones in chlorophyl, nanomagnetism by magnetotactic bacteria on single multifunctional devices.
