A highly sensitive NEMS capacitive sensor with electrode separation in the order of Debye length is fabricated for label free DNA analysis. The use of nano-scale electrode separation provides better insight in to the target-probe interaction which was not previously attainable with macro or even micro scale devices. As the double layers from both the capacitive electrodes merge together and occ...

In the paper an infinitesimally small segment of an interconnect has been initially considered and modeled as a two-port network which in turn allowed the modeling of a long interconnect as the cascading of several such networks. After the model order reduction by Pade-approximation various signal integrity losses, such as delay, overshoot, undershoot or glitch, etc. are estimated analytically ...

Highly n-doped silicon nanowires (SiNWs) with several lengths have been deposited via chemical vapor deposition on silicon substrate. These nanostructured silicon substrates have been used as electrodes to build symmetrical micro-ultracapacitors. These devices show a quasi-ideal capacitive behavior in organic electrolyte (1 M NEt4BF4 in propylene carbonate). Their capacitance increases with the...

Cathodic electrodeposited copper oxide thin films were prepared using 0.1 M aqueous (distilled water) copper sulphate solution onto the surface of stainless steel substrates. Deposited samples were characterized for structural and morphological analysis using XRD and SeM. Prepared samples were also analyzed using cyclic voltammetry, charge discharge and impedance spectroscopy. electrode shows n...

Nanostructured alpha-MnO(2) thin films with different morphologies are grown on the platinum substrates by a facile solution method without any assistance of template or surfactant. Microstructural characterization reveals that morphology evolution from dandelion-like spheres to nanoflakes of the as-grown MnO(2) is controlled by synthesis temperature. The capacitive behavior of the MnO(2) thin ...

Memristor, the missing fourth passive circuit element predicted forty years ago by L. O. Chua was recognized as a nanoscale device in 2008 by researchers of a H.P. Laboratory. Recently the notion of memristive systems was extended to capacitive and inductive elements, namely, memcapacitor and meminductor whose properties depend on the state and history of the system. In this paper, we use fract...

Abstract A grain moisture detection system is proposed in this paper, which is designed based on capacitive sensor and single chip microcomputer. The working principle of concentric capacitive sensor is introduced and the hardware circuits of system are described in details. The system has an intelligent controller internal, it can collect data, display data and determine whether to alarm when ...

This paper presents a new spherical shaped capacitive sensor device for creating interactive compositions and embodied user experiences inside of a periphonic, 3D sound space. The Somatic Sound project is here presented as a) technological innovative musical instrument, and b) an experiential art installation. One of the main research foci is to explore embodied experiences through moving, inte...

Corn moisture content is the main factor of effecting corn safe transportation and storage, and is also an indispensable measurement part when it is used to feed, food and industry. Due to large particle size, corn will produce large gap during measuring moisture content. Because air has much influence on dielectric constant of the device, moisture content is not precision. In all kinds of corn...
