چکیده

A novel instrumentation system has been designed for the correct detection of small dc currents emitted by characteristics points of the human skin using a non invasive probe. The probe presents an integrated pressure compensation system based on a force sensor allowing to obtain reliable and repeatable measurements that are virtually insensitive to pressure fluctuations. The current acquisition circuit and the pressure compensation system are illustrated together with experimental results.

A Sensitive Sensor for Nano-Molar Detection of 5-Fluorouracil by Modifying a Paste Sensor with Graphene Quantum Dots and an Ionic Liquid

5-fluorouracil is a widely used anticancer drug with many side effects on humans, and hence its analysis in biological samples is very important. Accordingly, a novel sensitive electrochemical approach was fabricated by incorporating graphene quantum dots (GCD) and 1-butylpyridinium bromide (BPBr) in the formulation of a carbon paste electrode (GQD/BPBr/CPE). The GQD was synthesized and charact...

A new strategy for controlling wind turbines against sensor faults and wake effects to harvest more electrical energy

This paper describes a new method for harvesting maximum electrical energy in wind farms. In proposing technique, the stochastic process principles are applied for detecting fault measurements of sensors. On the other hand, the wind farm is modeled by using fuzzy concept. Thereby the turbines are controlled against continuous changes in speed, direction and eddy currents of the blowing wind. To...

Tip sensor probe for changing refractive index measurement in small volumes

In this paper, a tapered tip optical fiber probe sensor for localized refractive index (RI) measurements is presented. This sensor’s interaction with analytes is confined to a few micro-meters which makes it a promising candidate for in-vivo or even intra-cellular RI monitoring. This tapered tip was simply fabricated by etching optical fiber with hydrofluoric acid to a conic shape with a sub-m...

Nile Blue- Chitosan Composite as a new Electrochemical Sensor for Uric Acid on Glassy Carbon Electrode

Nile blue-Chitosan NB-CH as a new type of organic days-organic composite was made using Nile blue and chitosan. The NB-CH composite was made using a 0.005 M solution of Nile blue NB and a 7 solution of chitosan. To do this, a mixture of Nile blue and Chitosan with the ratio of 2:1 was prepared. The electrocatalytic oxidation of uric acid UA has been studied on glassy carbon electrode by NB-CH u...

Sensitive Voltammetric Determination of Acetaminophen at Poly(4-vinyl pyridine)/Graphene Composite Modified Electrode

This study demonstrates the use of a selective and sensitive voltammetric sensor for determination of acetaminophen (AC). This was  performed by modifying a glassy carbon electrode with composite film of poly(4-vinylpyridine) and graphene sheet (P4VP/GR-GCE). The redox peak currents of AC increased significantly at P4VP/GR-GCE. The result was achieved by the synergistic effect of combined elect...
