Design and Simulation-Based Validation of an Embedded Acquisition Architecture for In Situ PCB Integrity Monitoring in Biomedical Devices

The reliability of biomedical devices is closely linked to the quality and long-term stability of the electronic circuits that support their operation. Printed circuit boards (PCBs), in particular, can be affected by manufacturing imperfections, thermal stress and progressive ageing, which may lead to failures during the device life cycle. In this study, we present the design and simulation-based validation of an embedded acquisition circuit aimed at monitoring PCB electrical integrity in a non-invasive and remote manner. The presented solution is based on Hall-effect current sensing combined with a 16-bit analog-to-digital conversion stage and a digital communication interface managed by a Raspberry Pi. This…
