Reference-Electrode Free pH Sensing Using Impedance Spectroscopy

We present a reference-electrode free sensor able to measure both pH and conductivity<br />based on impedance spectroscopy. The electrode is made of a layer of indium-tin-oxide (ITO). The<br />impedance of this electrode at low frequencies depends on its double layer capacity, which vari...
