Abstract

a presente invenção refere-se a um método para medição da impedância parasítica de pelo menos um traço de uma tira de teste biossensora (800), a tira de teste biossensora (800) compreendendo um eletrodo de trabalho (814a), um traço de eletrodo de trabalho (814c) operativamente acoplado ao eletrodo de trabalho (814a), um traço de trabalho de percepção (826c) operativamente acoplado ao eletrodo de trabalho (814a), um eletrodo contador (216a), um traço de eletrodo contador (216c) operativamente acoplado ao eletrodo contador (216a) e um traço de contador de percepção (224c) operativamente acoplado ao eletrodo contador (216a). o método compreendendo as etapas de seletivamente dispor um resistor dotado de uma impedância conhecida em série com o traço de trabalho de percepção (826c) e um traço de eletrodo de trabalho (814c) para formar um circuito em série dotado de uma impedância de circuito em série e compreendendo uma impedância conhecida do resistor e uma impedância de traço de trabalho de percepção (826c) e uma impedância de traço de eletrodo de trabalho (814c), seletivamente aplicar um estímulo para produzir uma corrente que passa através do circuito em série, medir o fluxo de corrente através do circuito em série, e usar a medição de corrente para calcular a impedância parasítica de pelo menos um traço da tira de teste biossensora (800).
