Web Technology Based Microelectrode Characterization Instrument

In order to track the on-going changes and ultimate reliability of neural recording and stimulation arrays, it is beneficial to regularly characterize electrode arrays within the use environment. Microelectrodes used for neural stimulation or recording research can have different behaviors in-vivo vs. in-vitro, and once implanted the success of the experiment often hinges upon knowing the stability, changes, or deterioration of the electrodes. This paper describes a new instrument that is capable of batch characterizing 16 electrodes using cyclic voltammetry, electrochemical impedance spectroscopy and charge injection measurements. The latest web based technology was applied to the software design, which greatly facilitates electrode data sharing among researchers.
