CMOS switches are one of the main components of today's analog circuits. Among the many types of non-idealities that can affect the performance of the switch, its leakage current is of utmost importance. In order to reduce the leakage current or equally increase the OFF resistance of any switch, a novel technique is presented in this paper. The proposed technique employs the body effect to incr...
A triboelectric nanogenerator composed of gold nanoflowers is demonstrated. The proposed triboelectric nanogenerator creates electricity by contact-separation-based electrification between an anodic metal and a cathodic polymer. For the improvement of output power via the enlargement of the effective surface area in the anodic metal, gold nanoflowers that produce a hierarchical morphology at a ...
Gold-gelatin bionanocomposite films are prepared by the reduction of gold ions by sodium borohydride in an aqueous solution. It is shown that both the solution and the films on glass substrates contain entrapped hydrogen micro- and nanobubbles with diameters in the range of 200 nm-3 μm. The optical properties of gold nanoparticles in the presence of gelatin and hydrogen nanobubbles are measured...
The aim of this study was to optimize candidate antigen proteins for serological screening of Chlamydia trachomatis infection. C. trachomatis positive serum and swabs of genital secretions were collected from 50 patients in the Tianjin Medical University General Hospital, as well as from 30 patients negative for C. trachomatis. Samples were assessed by colloidal gold assay in a sexually transmi...
The Astarghan copper-gold deposit is located about 50 km north of Tabriz, southeast of Kharvana, East-Azarbaidjan. The most important lithologic units in the area are a hypabyssal prophyritic granodioritic intrusive stock (Oligo-Miocene) and flysch-type sedimentry sequence consisting of limestone, limy sandstone and marl (Paleocene-Eocene). The plagioclases range in composition from oligoclase...
Becoming an Entrepreneur Using the 1996-2001 Chilean CASEN Panel Survey, this paper analyzes the impact on income of the switch from salaried employment to entrepreneurship (self-employment and leadership of micro-enterprises). By means of a difference-in-differences non-parametric matching estimator the paper alleviates problems of selection bias (on observable and unobservable traits) and cre...
In this paper, design, analysis and fabrication of a low loss capacitive RF MEMS shunt switch, which made on the coplanar waveguide transmission line and alumina substrate in the frequency band of 40-60 GHz, is presented. The CPW is designed to have 50Ω impedance matching on the alumina substrate. Then the desired switch is designed with appropriate dimensions. Afterward the important par...
This paper investigates the characteristics of a micro-switch that uses two side electrodes to open normally closed switch. The surround fixed electrode in well-known gap-closing configuration. can switch and be tuned respond appropriately outside forces. combined system dramatically improves control standard In conventional switches, DC voltage above certain value closes To reopen switch, diff...
Traditional MEMS actuators have limited stroke and force characteristics. This paper describes the development of a hybrid actuation solution, which utilizes a micro-machined actuator array to provide switching of mechanical motion of a larger mesoscale piezo-electric actuator. One motivating application of this technology is the development of a tactile display, where discrete mechanical actua...
