O desempenho de sensores fotoeletroquímicos, baseados no elétrodo Ti/TiO2 (sendo um exemplo de modelagem o sensor de hidrazina), foi descrito matematicamente e o respectivo modelo foi analisado por meio de teoria de estabilidade linear e análise de bifurcações. As condições do melhor desempenho destes sensores, bem como as de instabilidades oscilatória e monotônica, foram inferidas na base da análise do modelo.
The work of photoelectrochemical sensors, based on the Ti/TiO2 electrode (being an example for the modeling the hydrazine sensor), was described mathematically and the respective model was analyzed by means of linear stability theory and bifurcation analysis. The best response condition for this sensor, as also, the oscillatory and monotonic instabilities requirements, were inferred, basing on the model´s analysis.
