The satellite industry could experience its biggest revolution since it joined the ranks of commerce, thanks to some of the smallest machines in existence. Researchers are performing experiments designed to convince the aerospace industry that microelectromechanical systems (MEMS) could open the door to low-cost, high-reliability, mass-produced satellites. MEMS combine conventional semiconductor electronics with beams, gears, levers, switches, accelerometers, diaphragms, microfluidic thrusters, and heat controllers, all of them microscopic in s ....etc

ABSTRACT

Switching products technologies ranges from traditional Electro Mechanical Relays (EMR) and reed relays to semiconductor switches made of silicon or GaAs materials. A new type of device is currently getting to commercialization. The first sales of RF MEMS switches outside DOD programs have been realized by Teravicta in 2006. The achievements of RadantMEMS in USA DOD programs, the first commercial product sales from Teravicta in 2006 and the 4 other competitors (MEW, XCOMwirel ....etc

Compound solid state switches such as GaAs MESFETs and PIN diodes are widely used in microwave and millimeter wave integrated circuits (MMICs) for telecommunications applications including signal routing, impedance matching networks, and adjustable gain amplifiers. However, these solid-state switches have a large insertion loss (typically 1 dB) in the on state and poor electrical isolation in the off state. The recent developments of micro-electro-mechanical systems (MEMS) have been continuously providing new and improved paradigms in the field ....etc

1 .INTRODUCTION

In the 21st century, the nanometer will very likely play a role similar to the one played by the micrometer in the 20th century The nanometer scale will presumably pervade the field of data storage. In magnetic storage today, there is no clear-cut way to achieve the nanometer scale in all three dimensions. The basis for storage in the 21st century might still be magnetism. Within a few years, however, magnetic storage technology will arrive at a stage of its exciting and successful evolution at which fund ....etc

ABSTRACT
Recent advances in microelectromechanical systems, CMOS electronics and embedded computer systems will finally let us page link computer circuitary to neural cells in live animals. The key components of such a brain “computer system includes neural probes, analog electronics and miniature microcomputer. These bioembedded systems are called neurochips. By enabling better study of animal behavior™s neural basis, implantable computers may revolutionize field biology and event ....etc

ABSTRACT
The design, fabrication and testing of a novel neurochip structure for extracellular stimulation and recording of cultured neural networks are presented. The neurochip has 16 neuron wells, spaced 100 µm apart, in a 4 x 4 array, which are fabricated on a 9 mm by 3 mm silicon membrane, 20-µm-thick. The fabrication of the chips involves photolithography and micromachining on both sides of the membrane, which is located at the bottom of a 500-µm-deep cavity. Experimentally, the biocompatibility h ....etc

INTRODUCTION

Until recently, neurobiologists have used computers for simulation, data collection, and data analysis, but not to interact directly with nerve tissue in live, behaving animals. Although digital computers and nerve tissue both use voltage waveforms to transmit and process information, engineers and neurobiologists have yet to cohesively page link the electronic signaling of digital computers with the electronic signaling of nerve tissue in freely behaving animals.

Recent advances in micro electromechanical systems (MEMS), CMO ....etc

Bulk Micromachined Pressure Sensor



INTRODUCTION
pressure sensors have a wide-range of applications in
various fields, from automotive industry to medical
equipments, such as airbag system and respiratory devices. A
typical piezoresistive pressure sensor consists of two main
components: a diaphragm and resistors. They are two methods
of fabricating these parts: bulk (BM) and surface (SM)
micromachined. In the later one, the diaphragm is built on top
o ....etc
