This doctoral thesis explores innovative electronic applications in two distinct domains: harsh industrial environments and implantable medical devices.
Industrial Electronics (CHARM Project) The research addresses reliable data acquisition under extreme thermal stress, specifically for photovoltaic cell metallization processes. Three custom temperature data loggers (DLs) were developed to monitor industrial ovens. These include a "Harsh Environment" DL capable of operating up to 200°C without external protection. The devices utilize Platinum RTD sensors, custom firmware, and USB connectivity to ensure precise thermal control, enabling process optimization and fault avoidance in photovoltaic panel production.
Medical Technology (AUTOCAPSULE Project) The second focus is a Wireless Power Transfer (WPT) system for a robotic gastrointestinal capsule designed for active, minimally invasive diagnosis. Unlike passive commercial devices, this capsule requires continuous power for active sensing. The candidate developed the transmitter’s power section, comprising a TX Board with high-frequency GaN MOSFETs (operating at 1.7 MHz and 6.78 MHz) and a digitally controlled Variable Power Supply Board. A key feature is a back-telemetry system that dynamically regulates power based on feedback, ensuring functionality while preventing hazardous tissue overheating. The system was successfully validated via laboratory tests and in vivo porcine trials.
