The potential for complex microelectronics in the field of medical engineering is largely undeveloped. New therapy and early diagnosis measures could be developed with the help of complex microelectronics. For example, the quick detection of infectious diseases is still an unsolved problem, because the identification of microbes either requires their cultivation or DNA analysis in the lab. The development of point-of-care methods is a current development trend which requires further microtechnological impetus to generate innovative system solutions. Particularly understanding the boundary surface between biology and the sensor surface is a current research topic which can promote the advantages of electronic sensors. This requires a close cooperation with biology-oriented institutes or faculties.
