AbstractThis paper reports on the concept, design, fabrication andexperimental results of a new passive wireless sensor for pH measurements. Thesensor is based on a LC resonator formed by an inductor and an EIS (Electrolyte-Insulator-Silicon) capacitor working as a pH-to-capacitance transductor. Areference electrode is used to obtain a stable DC potential at the electrolyte.An additional comb-like electrode located on the surface of the insulator isalso provided to obtain a low AC impedance. Using this double-electrode scheme aQ larger than 15 is achieved for a wide range of conductivities. wireless measurements of the LC sensor yields a sensitivity of 1.0% frequency change perpH unit.
