SIUE Professors Receive Patent for Digital Potentiostat Circuit and System

October 28, 2014

 Mike Shaw      Brad Noble

SIUE’s Mike Shaw, professor and chair of the Department of Chemistry, and Brad Noble, associate professor of electrical and computer engineering in the School of Engineering, have received a patent (U.S. Patent Serial No. 13/371,230 issued as patent no. 8845870) for their Digital Potentiostat Circuit and System. The basic concepts that can be demonstrated with this device are relevant to studying batteries, fuel cells, and solar cells. According to Shaw, this “no frills” electrochemical and spectroelectrochemical methodology was designed to minimize cost, but still deliver high quality data, for teaching environments and labs.

Shaw and Noble believe that the scarcity of actual electrochemical practice at the freshman and sophomore undergraduate level is likely due to the expense to acquire reliable instrumentation. They plan to commercialize the units so that they can be incorporated into a broad range of educational settings for use by more undergraduates, high school students, and possibly home-schooled students.
