Microinstruments with integrated sensors and electronics are well adapted for remote environmental monitoring applications. Optimization of these microinstruments, however, has been difficult due to a previous lack of mixed-domain simulation environments. This work presents a complete electrode model for step-functional voltammetry with an insoluble species. The model includes the electrochemical response, sensor parasitics, sensor noise, and electrical instrumentation, and can be simulated in a standard electronic CAD environment. The simulation results are verified against experimental data taken using microfabricated sensors. Finally, the design environment is used to analyze system-wide design trade-offs.
