Interpreting electrochemical data in sensor/biosensor development

At Zimmer and Peacock there are a few keywords which define us, including: development, manufacturing, contract, electrochemistry, biosensors and medical diagnostics.


At Zimmer and Peacock we are always here to help our clients, customers and the community. If your electrochemical data looks like the adjacent figure then you are suffering what electrochemists call iR drop, what this means is that there is something in your measurement that is acting like a big resistor and it is distorting your data so you look like a resistor. What we mean by this is you show a linear relationship between voltage and current.


The sources can be variable but include:


1) A bad electrical contact.


2) A very non-conductive electrolyte.


3) An electrode with a coating on it that is very poorly conductive.
