These days, the market of wireless communications has developed dramatically. Thus, demand increased with respect to communication terminals that consume less power. Consequently, integration technology for passive elements and circuit module development ‘Radio frequency systems’ using ‘Micro electro mechanical system’ is becoming a focused topic. Many researchers various perspectives in this f...

We report a fast, high-throughput method to create size-tunable micro/nanoparticle clusters via evaporative assembly in picoliter-scale droplets of particle suspension. Mediated by gravity force and surface tension force of a contacting surface, picoliter-scale droplets of the suspension are generated from a nanofabricated printing head. Rapid evaporative self-assembly of the particles on a hyd...

This review presents a systematic perspective on the development of micro-optofluidic lenses. The progress on the development of micro-optofluidic lenses are illustrated by example from recent literature. The advantage of micro-optofluidic lenses over solid lens systems is their tunability without the use of large actuators such as servo motors. Depending on the relative orientation of light pa...

Several CMOS-MEMS tunable capacitors have been designed, fabricated and tested. Large-tuning ranges and high Q values are achieved. The structures were made from the CMOS interconnect stack using a maskless CMOS micromachining process. The 1 generation capacitors were fabricated using Austria Microsystems (AMS) 0.6 μm and Agilent 0.5 μm CMOS process. These devices have a measured nominal capaci...

optimal sitting and sizing of shunt capacitor banks at the distribution networks for the purpose of power quality improvement is drawn much attention of electric power utilities in the last decades. determining the optimal number, location and sizing of capacitor using bee colony optimization algorithm (bco) is being presented in this paper. the bco algorithm is a new population based meta-heur...

Variable capacitors are key elements in electrostatic micro-power generators. In such devices inertial forces are used to do work against the electric field of the capacitor, thereby converting mechanical energy to electrical potential energy that can be extracted by a suitable circuit. Applications are envisaged in portable, wearable or implantable electronic devices where body motion could pr...

In this paper we propose a novel method of realizing discrete-time (D-T) signal amplification using NanoElectro-Mechanical (NEMS) devices. The amplifier uses mechanical devices instead of traditional solid-state circuits. The proposed NEMS-based D-T amplifier provides high gain and operate on a wide dynamic range of signals, consuming only a few micro watts of power. The proposed concept is sub...
