Conductimetric pH sensor

Here, we describe the construction and evaluation of a conductimetric pH sensor, based on a multilayer polypyrrole film [8]. The sensor is an interdigitated electrode array coated with the polymer by using the Langmuir-Blodgett (LB) technique [9]. Impedance spectroscopy has been used to investigate the complex admittance of the device when exposed to aqueous solutions of different pH. [Pg.372]

The IDA electrode coated with an electroconductive polymer also serves as a conductimetric pH-sensitive sensor device [75,109]. Measurements of free-standing dry polypyrrole films [110,111] showed that the conduc-... [Pg.971]
