There is significant interest in the use of electrodes
for sensing or actuation in bio-fluidic microsystems.
Within these systems high levels of reliability are crucial
and complimented by requirements for extremely low
probabilities of false positive and false negatives. This
paper extends previous work on impedance and oscillation
based condition monitoring of electrode arrays by investigating the application of oscillation built-in self-test to microfluidic based electrodes for conductance measurements and a system level implementation for monitoring
multiple electrodes on-line.
