Micro Electro Mechanical Systems in biomedical industry
#1

ABSTRACT:

Micro Electro Mechanical Systems (MEMS) in the field of biomedical industry has given rise to Bio MEMS. These encompasses Biosensors, Bio instruments and tools, Bio testing and analysis etc. Bio MEMS present a great challenge to engineers to design and manufacture of these types of sensors and instruments. Biosensor serves as the interface between living and electronic systems. These systems and the sensors should not affect the behavior of the living systems. Thin “ film microelectronic technology offers special advantages for manufacturing of Biosensors over the traditional manufacturing methods. These can be used in minimizing the deleterious interactions through the use of small size and mass, Bio compatible material, and physical characteristics that are closely related to living tissues. Not only Bio MEMS the finger print sensor also discussed in this paper.

This paper also describes the concept and sensing principle of our fingerprint sensor, which we named as a MEMS finger sensor .Next, the analytical model of the MEMS structures described. Then, a fabrication process to stack the MEMS structures directly on the sensing circuits is presented. In the process, a sealing technique, STP (spin coating film transfer and hot-pressing) is applied. Finally, we discuss the fabrication results and evaluate the sensorâ„¢s ability to obtain fingerprint images regardless of whether the finger is dry or wet.

A Bio-MEMS is a special class of microelectromechanical systems (MEMS) where biological matter is manipulated to analyze and measure its activity under any class of scientific study.It is a exciting area of research in the field of microtechnology. biological and biomedical analysis and measurements and micro total analysis systems (TAS) are the most improtant applications based on this area.

Micro Total Analysis Systems
Also known as the lab on a
chip", miniaturized analysis systems, is growing rapidly. More than 25 years ago, the
first analytical miniaturized device fabricated on silicon, a gas
chromatographic analyzer, was presented. an injection valve and a separation column
1.5 m long was fabricated in a single silicon die. It was not until 1990 that
the reemergence of silicon-based analyzers took place with the
presentation of a novel work based on a miniaturized open-tubular
liquid chromatograph on a silicon wafer. Early theoretical considerations of the miniaturization concept
showed that electroosmotic pumping was an attractive and feasible
way to move aqueous media through interconnected channel. stacked modular devices in silicon and
plexiglass were designed and tested in in miniaturized flow
injection analysis (FIA).
