Potentiostat

Team Members: Kyle Bloomer Josh Geiman

Lucas Bennett

Dr. Cindy Harnett's laboratory is in need of around 15 potentiostats for testing a variety of devices

Background Info

What the system does How it works Expense of other commercial potentiostats Why it is important

Background info

Potentiostat holds Voltage constant and puts out the current needed

Galvanostat does vise versa

Doziers explanation

What we received from Ben 2 electrode vs 3 electrode Explanation of using Cheapstat instead of

Arduo

Background info

How to use it Application or example (preferably Chlorine

gen or fuel cell)

Background info

Potentiostat can be easily built by students Must cost under $100 Must have the ability to measure

Electrochemical potential Must be easy to use

Project Requirements

Function of system as an entity Measures characteristics of electrolytic cells Allocate PC come through USB to potentiostat via GUI(don’t use

the word GUI ;))

The Data/Display Management System manages three sub components

System control Software on the PC will provide the user with

means to specify the appropriate parameters Data logging

The PC will have the ability to keep records of the measurements returned from the Potentiostat

Data display After testing is successfully finished, the user will

have the ability to view results on the PC

The PC is connected to the potentiostat Software with a Graphical User Interface program will

run on a PC The user will have the ability to change configuration of

the test device through the GUI program to send to the potentiostat

Once the potentiostat is finished executing the test, the user will then receive the results through the software and have the ability to review them on the GUI.

Operational Concept

PC with USB connection For the Potentiostat to communicate with the PC, a

connection must be established through a USB interface DC Power Converter

A DC power converter must be utilized within the system to allow 120VAC, 60Hz, and 15A of operational power

External Interfaces

USB Connection Windows Operating System Software to Software Interface

Internal Interface

Intelligent Potentiostat Requirements The Potentiostat manages two functions

Data communication The function of this subcomponent is to

communicate all data from the PC Interfacing Control to the Potentiostat system

Device Under Test (DUT) measurement

Data/Display Management System The Data/Display Management System will handle

4 main requirements through C# Program Simplistic GUI for Data Controlling Transmit the configuration to the controller Initiates measurement process Retrieves raw data

Data/Display Management System Software

The PC Software will allow user to configure the test profile The user will have the ability to select various waveforms

and also set the maximum voltage applied by the potentiostat

The results of each measurement will then be reported back to the user

System Description

CheapStat Parts have been ordered Designing the GUI portion of the PC Software to best

fit requirements Testing preexisting Cheapstat code set
