claim that low-flow mass controllers are effective is backed up with important information from different sources that address the effectiveness of mass controllers in semiconductor processing. The researchers make comparisons between the microelectromechanical devices and the current technology and state that these devices are ultra-small in size, making it possible to minimize dead volumes and gas contact surface areas. This claim helps in understanding how effective and efficient these devices

Microelectromechanical systems have found wide commercial applications owing to the research and development in this field. For example, arrays of micromechanical mirrors are greatly used in the optical communications industry. Other uses of micromechanical systems include Ink-jet printers and accelerometers which are used in the automobile industry. Advancement in the silicon based fabrication technology has made it possible for a range of MEMs sensors and actuators to be put to practical use. MEMs

Capacitive sensors use an array capacitor plates to image the fingerprint. Skin is conductive enough to provide a capacitive coupling with an individual capacitive element on the array. Ridges, being closer to the detector, have a higher capacitance and valleys have a lower capacitance. Some capacitive sensors apply a small voltage to the finger to enhance the signal and create better image contrast. Capacitive sensors can be sensitive to electrostatic discharge (shock) but they are insensitive

Overview Arduino Pro A huge variety of microcontrollers already exist on the market. After comparing several types of boards, including ATMEL, INTEL and PIC based ones; an ATmega328 based ship was assigned for the implementation of our prototype: The Arduino Pro, which is cheaper in price and smaller in size than the other boards, and satisfies perfectly our needs. The Arduino Pro comes in both 3.3V/8MHz and 5V/16MHz versions. After benchmarking these two existing boards, the 5V/16MHz one was chosen

IoT. The sensor market is enormous, with Analog Devices estimating it to approach $100 billion annually, much of which is not related to semiconductors at all. The sensor market applicable to semiconductor vendors includes micro-electromechanical systems (MEMS) - based sensors, optical sensors, ambient light sensors, gesture sensors, proximity sensors, touch sensors, fingerprint sensors and more. These chips effectively detect changes in the environment, creating the information that is ultimately

being used in the real time environment i.e., in a closed loop operation. So many advancements in the MEMS technology make the MEMS production very effective, but still there are some drawbacks in its structure and in its performance, which pulls the system efficiency to down. Self and mutual inductions are the two major run time defects which affects the performances of the MEMS devices and increases its power consumption when there is a physical data link between two blocks. If the proper steps are
