This presentation introduces MEMS and microfluidics technology for biomedical applications, including their appli-cations with examples from the literature. BioMEMS projects at METU-MEMS Center will be presented.

Since the first introduction in 1970’s, MEMS technology is becoming popular in many different application areas, including military, automotive, and consumer electronics, as it provides cheap, small, and smart sensors and actua-tors. This technology is especially critical for biomedical applications, resulting in a new research area shortly called BioMEMS. BioMEMS can be defined in general as “devices or systems constructed using techniques inspired from microfabrication that are used for processing, delivery, manipulation, analysis, or construction of biological and chemical entities.” Application areas of BioMEMS range from diagnostics to micro-fluidics, systems for drug delivery, tissue engineering, and implantable systems.

One of the most interesting application areas for this technology is the micro total analysis systems (Micro-TAS). Bio-logical samples can be analyzed in a very small area with considerably reduced cost and time, by forming micro-flu-idic channels on silicon substrate and combining them with onchip electronics. Some examples for such applica-tions include on-chip electrophoresis systems, polymerized-chain reaction (PCR) units, DNA sequencing chips, and complex lab-on-a-chip devices.

There are currently various BioMEMS related projects going on at METU-MEMS, including DNA electrophoresis systems, dielectrophoresis chips for cell seperation, gravimetric sensors for cancer cell detection, microvalves and pumps for lab-on-a-chip systems, and electrochemical sensors for bacteria and toxin detection.

Haluk Külah received B.Sc. and M.Sc. degrees in electrical engineering with high honors from METU, Ankara, Turkey, in 1996 and 1998, respectively. He received Ph.D. degree in electrical engineering from the University of Michigan, Ann Arbor, in 2003. From 2003 to 2004, he was employed as a Research Fellow at the Department of Electrical Engineering and Computer Science, the University of Michigan. Dr. Külah joined the Electrical and Electronics Engineering Department of METU as a faculty member in August 2004. He is also the Deputy Director of METU-MEMS Research and Applications Center since 2008. His research interests include MEMS, MEMS-based energy scavenging, microsystems for biomedical applications (BioMEMS), and mixed-signal interface electronics design for MEMS sensors. Dr. Külah has more than 130 international publications, 15 national/international patents, and 8 international patent applications. He has been awarded with 2009 Research Encouragement Award by Prof. Mustafa PARLAR Education and Research Foundation, 2013 Research Encouragement Award by TÜBİTAK, 2013 IBM Faculty Award, and 2015 Young Scientist Award by Turkish Science Academy. Dr. Külah has received EU Horizon 2020 2015 ERC Consolidator Grant by FLAMENCO project, which is on autonomous and fully implantable cochlear implants.
