    Abstract

    We developed a novel solid rumen pH sensor for long-term cow health condition monitoring. The pH sensor is composed by a sensing electrode with indium tin oxide (ITO) layer and a measuring unit of metal-oxide-semiconductor field-effect transistor (MOSFET). Sensor system can be fabricated with a compact size by getting rid of the reference solution. By MEMS technique, solid pH sensors were fabricated well and given sensors have the measuring sensitivity of > 14 μA/pH. The long-term test with interval experiments have been finished, as the results shown, developed pH sensor has a stable performance for relative long time rumen pH value measurement.
