Title: Portable Low-Cost Instrumentation for Field Ready Electrochemical Experimentation

 

Invention: The invention describes a low cost, Arduino-based potentiostat for electrochemical measurements that is capable of performing relevant electrochemical tests. This potentiostat can run on five-volt batteries and stores data that can be readily exported.

 

Background: Measurement science has continually evolved since the introduction of the operational amplifier, the charges curled device, and the microcontroller. Arduino (computer hardware, software, and microcontroller based kits) provides a cheap means of computing to perform calculations in the field. These two can be brought together in a revolutionary new platform for performing laboratory grade measurements on field samples.

 

Applications:

  • Educational tool for students (i.e. study of electrochemistry)
  • Field experimentation and research tool

 

Advantages:

  • Relatively cheap to produce (approximately $100)
  • Allows for highly relevant tests to be run in the field if laboratory equipment is not available
  • Arduino is an open source platform, allowing additions to the main unit to be made easily
