Smart sensors in the broadest sense are sensors that are combined with dedicated hardware or software to produce a performance and/or functionality that goes greatly beyond that of the raw sensor. As such, smart sensors bear the potential to revolutionize all aspects of our everyday life, ranging from smart homes that benefit from ambient assisted living, optimized production lines in the frame of Industry 4.0 to high-end sensors that enable entirely new experiments in the scientific world.

In this talk, we will investigate the use of smart sensors in the latter field of high-end sensing for scientific applications and discuss how the multiphysics and advanced modeling aspects of state-of-the-art smart sensors are crucial for their performance.

To this end, we will discuss examples of biomedical quantum sensors that greatly benefit from the embedding of the interface electronics for enhanced performance. It will be discussed how an advanced modeling of the sensor together with a precise modeling of the interface electronics as nonlinear dynamical system can be used for co-designing sensor and electronics to improve the overall system performance. Finally, we will talk about the challenges in numerical simulations of such advanced sensor systems, which arise from the immense precision (often precisions of 10-9 or better are required) that is frequently required in the scientific context.
