Abstract:
Electrochemical sensors with sensitive membranes from amorphous materials, in particular, in case of pH electrodes are traditionally fabricated by glass-blowers. For a more effective manufacturing, sometimes so-called blowing machines are used. Thereby, on the one hand a miniaturisation of these electrodes is limited due to technological reasons. On the other hand, this makes it impossible to achieve planar sensors. In addition, a relatively large amount of functional special glass is necessary for such processes. Pulsed laser deposition (PLD) could provide ideal conditions to reduce the above-mentioned drawbacks. In this contribution results of using this method for the fabrication of planar glass based electrochemical sensors are demonstrated, whereby an amorphous silicate glass is in the focus for the sensor membrane.
