Simulation of Interdigitated Electrodes (IDEs) Geometry Using COMSOL Multiphysics

International Conference on Intelligent and Advanced Systems, 2018
Interdigitated Electrodes (IDEs) based sensor in comb-like electrodes structure is also an attractive candidate in gas sensor and biosensor applications, owing to its simple structural design. The sensitivity can be improved based on geometric parameters

Zinc oxide interdigitated electrode for biosensor application

AIP Conference Proceedings, 2016
In 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.

Fluid characterization by interdigitated electrodes sensors

2009
The 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.

Nanoscaled interdigitated electrode arrays for biochemical sensors

Proceedings of International Solid State Sensors and Actuators Conference (Transducers '97), 2002
Nanoscaled interdigitated electrode arrays were made with Deep U.V. lithography. Electrode widths and spacings from 500 nm down to 250 nm were achieved on large active areas (0.5 mm/spl times/1 mm). These electrodes allow for the detection of affinity binding of biomolecular structures (e.g. antigens, DNA) by impedimetric measurements. Such a sensor is

Electrical conductivity measurements using microfabricated interdigitated electrodes

Analytical Chemistry, 1993
Microfabricated interdigitated electrode arrays were constructed and evaluated for use as miniature conductivity cells. The arrays were 2×3 mm in size and had digits ranging in size from 10 to 80 μm. The complex electrical impedance of the devices was measured at frequencies spanning from 100 to 100 kHz in solutions with resistivities ranging from 10 ...

Magnetoelectric thin film composites with interdigital electrodes

Applied Physics Letters, 2013
Magnetoelectric (ME) thin film composites on silicon cantilevers are fabricated using Pb(Zr0.52Ti0.45)O3 (PZT) films with interdigital transducer electrodes on the top side and FeCoSiB amorphous magnetostrictive thin films on the backside. These composites without any direct interface between the piezoelectric and magnetostrictive phase are superior to

Interdigitated electrode biosensor for DNA sequences detection

2015 27th International Conference on Microelectronics (ICM), 2015
In this work, we present the design of a biosensor for specific DNA sequences detection. Bioimpedance spectroscopy (BIS) is used to characterize DNA hybridization. This theoretical study allows to optimize the geometric parameters of the biosensors by reducing the cell factor (Kcell), where the CoventorWare software was used to modelize the biosensors ...

Intense terahertz antenna array with interdigital electrodes

SPIE Proceedings, 2008
In this work a powerful terahertz antenna array with interdigital electrodes is fabricated, and the performance of one antenna unit is compared with a conventional resonant dipole antenna. The antenna unit has a better capacity of generating THz wave compared with a conventional resonant dipole antenna at the same bias electrical field and the same ...

Underwater Ultrasonic Wave Transducer Using Interdigital Electrodes

Japanese Journal of Applied Physics, 1982
An interdigital transducer (IDT), developed to excite surface acoustic waves, can emit longitudinal waves directly into liquid. The method of obtaining a convergence acoustic beam by designing the pattern of IDT is discussed in this paper. Also shown is that the acoustic reflection image of an object placed in water can be taken using the ...

Interdigitated electrode modelling for applications in dielectrophoresis

2011 IEEE ICMTS International Conference on Microelectronic Test Structures, 2011
Electrical test structures have been designed to enable the characterisation of interdigitated electrode structures in conductive solutions, as used in dielectrophoresis. Test masks have been fabricated to explore the impact of array size, finger separation and solution conductivity on the applied electric field.
