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
