FLEXIBLE PH SENSOR WITH POLYANILINE LAYER BASED ON IMPEDANCE MEASUREMENT

A flexible sensor with conducting polyaniline layer for detecting pH value based on the impedance measurement is fabricated and demonstrated in this study. The pH sensor consists of an interdigital electrode array on a flexible printed circuit and a thin-film polyaniline as the sensing layer. As the conductivity of polyaniline depends on the redox state, the impedance change of the polyaniline after it has reacted with different pH value solutions works as the sensing mechanism. In order to

AN ELECTRICAL MODEL OPTIMIZATION FOR SINGLE CELL FLOW IMPEDANCE SPECTROSCOPY

This paper presents an optimization of a single cell electrical model, based on Maxwell’s mixture Theory, applied to flow cytometry coupled to impedance spectroscopy. It is based on the discretization of the measurement area into a square reference volume, centered between micro-electrodes, and fixed impedance areas. The first one represents the sensing area, the one impacted by cell presence during measurement, and the second one, all other areas that contribute to global measured impedance

An Experimental Assessment of PZT Patches for Impedance-Based SHM Applications

In this paper, we present an alternative method for assessing the sensitivity of lead zirconate titanate (PZT) piezoceramics for damage detection in structural health monitoring (SHM) systems based on the electromechanical impedance (EMI) principle. An assessment of the sensitivity is obtained experimentally using the pencil lead break (PLB) method, which is frequently used in acoustic emission (AE) systems. Tests were carried out on an aluminum beam, and the results show a clear relationship

Zirconia potentiometric oxygen sensor activation using NEMCA

NEMCA known for the increasing the catalytic activity/selectivity of the gas exposed electrodes was investigated for the potentiometric zirconia oxygen sensor activation. Electrochemical promotion of O2-sensors with Pt-cermet electrodes aged in the field was significant with up to 5 times in the impedance reduction. Stability test on the NEMCA activated O2-sensors was showing just a minor impedance increase. Sensor response time was reduced by NEMCA effect by ~5-10% with up to 3 times signal

Impedance Behaviour of a Microporous PMMA-Film `Coated Constant Phase Element' based Chemical Sensor

In this work, it has been attempted to characterize a new type of impedance sensor called constant phase element (CPE) sensor; which has microporous PMMA- lm coating on the electrode surface. It has been shown that the `constant phase angle (CPA)' behaviour is primarily due to the porous structure of the electrode surface. And the phase angle at the output of the sensor changes with thickness variation of the PMMA coating and ionic property of the medium in which the sensor is dipped in. The

A circuit design with bespoke control software is described which has delivered precision in electrical impedance measurements of ~ 10ppm, after calibration. It is low-cost and applicable to jobs such as direct measurement using a sensor whose resistance changes with some physical quantity of interest; calibration at end of line in the production of such sensors; or calibration of equipment which may be out of warranty. It was developed using resistance temperature detectors (RTDs).

Bandwidth enhancement for thin substrate UHF RFID patch antenna

Introduction Most commercial UHF RFID patch antennas are either made from thick substrate (usually 1/10th of the wavelength) or has a stacked patch configuration to achieve the necessary operating bandwidth. This paper presents an unconventional and inexpensive way to enhance the impedance bandwidth of a thin substrate (1/35th of the wavelength) microstrip fed patch antenna. The 902–928 MHz RFID band was chosen for demonstration as it is the widest RFID bandwidth allotted by Federal
