study of mem Relay Contact design and body bias effects on on state resistance stability
IEEE\ ASME Journal of Microelectromechanical Systems, 2020Co-Authors: Benjamin Osoba, Sergio F Almeida, Urmita Sikder, Tsegereda Kedir Esatu, Tsujae King LiuAbstract:Body-biased micro-electro-mechanical (MEM) Relays previously have been demonstrated to be a promising alternative to transistors for ultra-low voltage digital logic applications. A basic requirement for reliable Relay-based circuit operation is suitably low and stable Relay ON-state resistance ( $R_{\mathbf {ON}}$ ). In this work, the effect of body biasing on $\text{R}_{\mathbf {ON}}$ is investigated for Relays of different Contact designs. It is found that a single direct Contact design not only provides for the smallest hysteresis voltage but also the smallest $R_{\mathbf {ON}}$ , making it the most suitable for low voltage applications. Body-biased operation is found to degrade $R_{\mathbf {ON}}$ stability over many ON/OFF switching cycles, however, due to a reduction in Contact velocity. [2020-0297]

reducing adhesion energy of nano electro mechanical Relay Contacts by self assembled perfluoro 2 3 dimethylbutan 2 ol coating
AIP Advances, 2019Co-Authors: Sara Fathipou, Sergio F Almeida, Ivas Saha, Farnaz Niroui, Tsujae King LiuAbstract:To enable energy-efficient electronic devices for the future, nano-electro-mechanical (NEM) Relays are promising due to their high ON/OFF current ratio and potential for low operating voltage. To minimize hysteresis and, consequently, Relay operating voltage, it is imperative to reduce the Relay Contact adhesion, which can be achieved by coating the Contacts with anti-stiction self-assembled monolayers. Herein we report a 71% reduction in hysteresis voltage by utilizing a branched perfluorocarbon antistiction molecule: Perfluoro (2,3-Dimethylbutan-2-ol) (PDB) on top of the tungsten Contact surfaces. Experimental results show the operation of a PDB-coated NEM Relay with abrupt switching, undetectably low OFF-state current, hysteresis voltage as low as 20 mV, and a large ON/OFF current ratio (>107).To enable energy-efficient electronic devices for the future, nano-electro-mechanical (NEM) Relays are promising due to their high ON/OFF current ratio and potential for low operating voltage.

Mathematical logic as a mean of solving the problems of power supply for buildings and constructions
IOP Conference Series: Earth and Environmental Science, 2017Co-Authors: Igor Pryadko, Ekaterina Nozdrina, Andrey BoltaevskyAbstract:The article analyzes the questions of application of mathematical logic in engineering design associated with machinery and construction. The aim of the work is to study the logical working-out of Russian electrical engineer V.I. Shestakov. These elaborations are considered in connection with the problem of analysis and synthesis of Relay Contact circuits of the degenerate (A) class which the scientist solved. The article proposes to use Shestakov's elaborations for optimization of buildings and constructions of modern high-tech. In the second part of the article the events are actualized in association with the development of problems of application of mathematical logic in the analysis and synthesis of electric circuits, Relay and bridging. The arguments in favor of the priority of the authorship of the elaborations of Russian electrical engineer V. I. Shestakov, K. Shannon – one of the founders of computer science, and Japanese engineer A. Nakashima are discussed. The issue of contradiction between V. I. Shestakov and representatives of the school of M. A. Gavrilov is touched on.

the problem of using logic in structural mechanics and electrical engineering as viewed by the russian researcher boris biryukov
Procedia Engineering, 2016Co-Authors: Igor Pryadko, Alexander IshkovAbstract:Abstract The authors consider innovative materials and structures developed by Boris Biryukov, a Russian researcher, within the framework of structural mechanics and civil engineering. The authors analyze the contribution made by Boris Vladimirovich Biryukov, an outstanding Russian logician, into the development of applied logic in Russia. In 1962 – 1991, Boris Biryukov headed the methodology department of the Cybernetics Research Council at the USSR Academy of Sciences. In some of his works, Biryukov interpreted the ideas initially expressed by N.M. Gersevanov, V.I. Shestakov, P. Erenfest and other logicians and mathematicians, who applied the methods, originally developed within the framework of exact and natural sciences, to technology-related problems of the national economy. The authors prove that Boris Biryukov and his colleagues were the first scholars who drew the attention of the research community to the logic-based research performed by N.M. Gersevanov, a prominent engineer and urban developer. In his works, Biryukov proved that this founder of the Russian school of soil mechanics was the first researcher who applied the instruments of mathematical logic to civil engineering problems. In the second part of the article, the authors demonstrate the way V.I. Shestakov developed several Gersevanov's ideas. Finally, the authors offer a sample Relay Contact circuit applied to the identically true formula compiled according to the rules of the logic of sentential calculus.

Timed Relay Contact closure controlled system for parallel second dimensions in multi-dimensional liquid chromatography
BMC Research Notes, 2019Co-Authors: William Craig ByrdwellAbstract:ObjectiveShort-chain triacylglycerols (TAGs) in lipid extracts of biological samples are not sufficiently resolved using conventional reversed-phase separation on two C18 columns in series, or using a two-dimensional chromatographic separation with a silver ion column as the second dimension (^2D). An additional dimension of separation was required.ResultsThe hardware and software components to allow a second second-dimension (^2D) separation and three total separation dimensions were developed. Two Contact closure (CC) activated 4-port, 2-position valves (4P2PVs) for ultra-high performance liquid chromatography (UHPLC) were joined together and used for one of two second dimensions in comprehensive two-dimensional liquid chromatography (2D-LC) coupled to four mass spectrometers simultaneously in parallel in an LC1MS2 × (LC1MS1 + LC1MS1) = LC3MS4 configuration. A timed Contact closure circuit (TCCC) controlled the two UHPLC valves, operated by repetitive CCs for the 4P2PVs. The TCCC-controlled 4P2PVs were used to direct a portion of the ^1D eluent to one of the two ^2D’s for separation by a quaternary UHPLC system that was not allowed by the commercial 2D-LC system. The ^1D separation was a non-aqueous reversed-phase HPLC instrument used for separation of TAGs; the commercial 2D-LC ^2D binary UHPLC was used for silver-ion chromatography of unsaturated TAGs; and the CC-controlled second ^2D was used for separation of short-chain (SC) saturated TAGs.
