Abstract

Puede ser particularmente difícil medir el pH in vivo usando sensores electroquímicos de corriente debido a la deriva del sensor y ensuciamiento de la superficie del sensor. Los sensores adecuados para medir pH, en particular in vivo, pueden comprender: una cola de sensor que comprende un primer electrodo de trabajo, un segundo electrodo de trabajo y al menos otro electrodo; una primera porción activa ubicada sobre el primer electrodo de trabajo, la primera porción activa que comprende una sustancia que tiene una química de oxidación-reducción dependiente de pH; y una segunda porción activa ubicada sobre el segundo electrodo de trabajo, la segunda porción activa que comprende una sustancia que tiene una química de oxidación-reducción que es sustancialmente invariante con el pH. Una diferencia entre una primera señal desde la primera porción activa y una segunda señal desde la segunda porción activa puede correlacionarse con un valor de pH para un fluido.
