Fluid characterization by interdigitated electrodes sensors
2009The purpose of this paper is to present the concept of a complete fluid characterization microsystem. This system is composed of three parts. The first is a classical two-dimensional sensor using interdigitated (IDA) aluminum electrodes covered by anodized alumina. The second part is a CMOS digital circuit which is used to modulate the sensor topology.

Fluid streaming above interdigitated electrodes in dielectrophoresis experiments
ELECTROPHORESIS, 2011AbstractFor the investigation of alternating current electrokinetic effects, a system is presented that allows for the simultaneous observation of fluid flow above and around microelectrodes in all three directions in space. Beside the usual microscopical view from top, lateral observation through the same objective is made possible by two small ...

3D interdigitated electrode array in the microchannel free of reference and counter electrodes
Biosensors and Bioelectronics, 2018We demonstrate the three-dimensional (3D) interdigitated array (IDA) chip that operates without reference and counter electrodes, which are necessary components to apply enough potential to trigger the intended redox process, but used unwieldy for chip-based electrochemical detection.

Driving power for light modulators with interdigital electrodes
Optics Communications, 1975Abstract Surface field distribution induced inside an electro-optic crystal by a set of interdigital electrodes are examined more rigorously than in a previous paper about surface field electro-optic light modulators. Capacitance, effective modulating voltage, and required driving power for the modulator are calculated as a function of a structural ...

Zinc oxide interdigitated electrode for biosensor application
AIP Conference Proceedings, 2016In biosensors, zinc oxide (ZnO) thin film plays a crucial role in term of stability, sensitivity, biocompatibility and low cost. Interdigitated electrode (IDE) design is one of the device architecture in biosensor for label free, stability and sensitivity.

The dependence of the capacitance of ferroelectric film-based interdigital capacitors (IDC) on the electrode configuration has been investigated using the Gevorgiann model. The electrode spacing, width, overlapping length, thickness and electrode 'finger' number have different influences on the capacitance.

To power the tiny sensor devices by MEMS generator which scavenging energy from ambient vibrations is becoming practical due to the power consumption of low power electronics is going down to tens to hundreds μW for integrated wireless sensor devices. In this paper, we are going to present the development on two different types of piezoelectric MEMS

Continuum properties from interdigital electrode dielectrometry
IEEE Transactions on Electrical Insulation, 1988Using a modal approach, a model is derived that makes the interdigital electrode microdielectrometer developed by S. D. Senturia et al. (J. Adhesion, vol.15, p.69-90, 1982) applicable to measuring continuum parameters in a wide range of heterogeneous media.

Interdigitated coplanar electrodes for enhanced sensitivity in a photorefractive polymer
Optics Letters, 2011Organic photorefractive polymer composites can be made to exhibit near 100% diffraction efficiency and fast writing times, though large external slants are needed to project the applied field onto the grating vector. We show here that the use of interdigitated electrodes on a single plane provides similar performance to these standard devices and ...
