A novel sensor system is introduced featuring real-time in-situ monitoring of biodegradation processes. The system measures changes of the electrochemical properties of the polymer under investigation to quantify the progress of the degradation process. As a result, a higher time resolution is achieved and higher throughput can be realized compared to common measurement techniques. The obtained results demonstrate the potential of field-effect sensors as promising non-destructive tool for the real-time monitoring of polymer degradation.
