Ion-selective electrodes have been proven useful in water analysis. They are usually used as single-rod measuring chains in different designs, which are manufactured using precision mechanical manufacturing and assembling technologies. The paper describes a microsystem technology approach for the fabrication of miniaturized electrochemical sensors. Design, manufacture, and performance of the novel ceramic multilayer-based sensor array are presented in the paper using various examples.

A novel, low-cost measurement device for simultaneous high temperature measurements of the electrical conductivity and Hall coefficient has been developed. Simulations were used to design a suitable screen-printed planar platinum heating structure that generates temperatures of up to 600 °C. Simulations of the temperature distribution have been validated using thermal imaging. Measurements were compared with data from the literature to validate the functionality of the novel device.

NiCr-carbon thin-film strain gauges offer the outstanding characteristic of a very high strain sensitivity. This can be very advantageous for many high-precision mechanical sensors like load cells. A downside of sensors based on these NiCr-carbon strain gauges is a rather large creep error, meaning reversible signal deviations at a constant load. We present two applicable methods for adjustment of the creep error: a modification of the film composition and a modification of the strain transfer.
