ABSTRACT

In this chapter it is proved that with thick-film technology, planar voltam-metric sensors can be produced. A working thick-film glucose sensor realized by the authors and a commercial blood glucose test strip based on a ferrocene biosensor manufactured by MediSense is discussed. A new range of planar voltammetric sensors has been developed by the authors using screen-printing technology. A new range of planar voltammetric sensors has been developed by the authors using screen-printing technology. The world-wide interest in publications indicates that thick-film technology applied to the development of planar voltammetric sensors is a worthy alternative to high-cost ic technology and labour-intensive manual production methods. Packaging of thick-film sensors is easy if the sensors are large. Due to the larger dimensions, a higher current is measured at the electrodes, so leakage currents are not that important.
