Computer-Controlled Voltage/Current Source and Response Monitoring System for Electrochemical Investigations

Abstract

In this paper, a computer-controlled voltage and current source, together with a response monitoring system for electrochemical investigations, is presented. The measuring system consisted of two major parts: the measuring hardware (HW) and the proprietary software. The hardware included the data acquisition USB card NI USB 6211 from National Instruments Company as well as all needed circuits (the analogue front end, the signal conditioning circuits, and power supplies). The software is based on the LabVIEW platform from National Instruments, and it is designed to control the signal generation and measurements, to cancel the noise in the signals, and to calibrate the device. The supported electrochemical methods are potential, potentiostatic and galvanostatic measurements, as well as the cyclic voltammetry and impedance measurments. The system was thoroughly tested, and it was determined that the system characteristics fulfil the requirements for most of the electrochemical and bioelectrochemical measurements, supercapacitor characteristics investigations, and much more. The overall system is modular; the HW and SW can easily be upgraded to support different methods and purposes and, therefore, the performance of the system.

Supercapacitors: The Innovation of Energy Storage

“…Several experiments were performed using this method and it has been verified and determined that it can be applied for rapid characterization of electrochemical systems. The experiments were carried out using a system for electrochemical tests based on a PC and the LabVIEW software package (Figure 13) [31].Thesystem is designed to cover most electrochemical tests in wide ranges, both at the level of the electrochemical cell, and at the level of the completed supercapacitor (Figure 14) [32].…”

“…The obtained temperatures are shown on the displays Ti ( • C) and diagrams (XY Ti) and finally saved in the form of a text file whose name is specified before starting the measurement. The program was able to be stopped at any time by clicking the STOP button[21].…”
