Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single sensor configuration is used, then the device complexity is low, but the measurement precision is insufficient for exact fluid characterization
Solution Approach 1:
The sensor material is divided into multiple sensor configurations with different properties (e.g., different layer thicknesses, different temperatures, different functionalizations). Each configuration provides a distinct temporal change response to fluid constituents, enabling precise fluid characterization through comparative analysis of multiple segmented measurements rather than a single measurement.
2Measurement precision
If multiple sensor configurations are implemented, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
Multiple sensor configurations are merged into a single integrated sensor structure. Different sensor configurations (with varying layer thicknesses, temperatures, or functionalizations) are combined within one sensor device, sharing common components such as the substrate and measurement electronics. This merging approach enables precise constituent differentiation while reducing overall device complexity compared to using separate sensor devices.

AI summary
A fluid sensor comprises a sensor material configured to come into contact at a surface region of same with a fluid and to obtain a first temporal change of a resistance value of the sensor material on the basis of the contact in a first sensor configuration and to obtain a second temporal change of the resistance value of the sensor material on the basis of the contact in a second sensor configuration. The fluid sensor comprises an output element configured to provide a sensor signal on the basis of the first and second temporal change of the resistance value.
