The detection of chemical substances at trace amounts can be a difficult task that requires typically laboratory equipment and skilled technical support. In this European research project, we develop with partners a miniature automated laboratory system for autonomous operation in harsh conditions. This system is projected to detect specific chemical substances at concentration levels in the range of the micro-mole per liter in the waste water.
The Fraunhofer IIS focuses on the design of a readout ASIC for chemical sensors and the development of energy harvesters for the sewage environment. The implementation of bias and readout electronics for chemical sensors with a low-power integrated-circuit technology is the key to the success of the project.
