Scientific Description
MEMS activities at METU started in 1995 within the Electrical and Electronics Engineering Department. Since then a number of research projects have been conducted that are supported by various national and international institutions, including TUBITAK, the State Planning Organization (DPT), MSB Ar-Ge, SSM, the European Union's 6th and 7th Framework Programmes, NATO SfS Programme, NSF, TOFAS, and Intel.

As a result, a considerable amount of knowledge and experience has been gained, and the first MEMS center was established in Turkey in 2008 as the METU-MEMS Center. At the METU-MEMS Center a wide variety of microsensors and components has been and is being developed, including low-cost CMOS infrared detectors, accelerometers, gyroscopes, DNA analysis systems, biosensors, micro power generators, chip cooling systems, acoustic sensors, humidity sensors, temperature sensors, frost sensors, piezoresistive and capacitive pressure sensors, and various RF MEMS components. Some of the developed prototypes show performance comparable to the best examples in the world, and efforts to commercialize these microsensors and microsystems are continuing.

In the past 15 years, the METU-MEMS Center has collaborated with a number of national/international partners such as IMEC (one of the largest microelectronics/MEMS center in Europe), Intel, the University of Michigan at Ann Arbor, Arizona State University, the Massachusetts Institute of Technology, ASELSAN, TOFAS, and ARCELIK (also known as BEKO). With the help of these collaborations and the success of the projects, the METU-MEMS Center has gained well-deserved recognition both in national and international arenas. Based on this reputation, the IEEE/ASME MEMS 2006 conference was held in Istanbul, Turkey. The Center has recently been awarded a European Union 7th Framework Programme (EU-FP7) Regional Potentials (REGPOT) Project (METU-MEMS).

The current goal of the METU-MEMS Center is to be a center of excellence in MEMS field, serving national and international research and technology for industrial development.
