Descrizione Inductive wireless power transfer (IWPT) represents a significant advancement for biomedical applications, enabling the powering of implants and medical devices without the need for invasive wires. Achieving high efficiency in power transfer is essential, and optimizing the design of the transmitting and receiving coils is crucial.
This thesis proposes the design and optimization of a planar spiral coil to maximize power transfer efficiency (PTE). The project involves simulating and testing various spiral coil shapes using Ansys software to evaluate PTE, Specific Absorption Rate (SAR), and temperature profiles. Different configurations of planar spiral coils will be designed and analyzed to determine the optimal design. The simulations will provide insights into the performance characteristics of each design, focusing on maximizing efficiency while minimizing SAR and thermal effects. The most promising designs will be fabricated on a PCB (Printed Circuit Board) and subjected to real-world testing to validate the simulation results.
Expected outcomes include a prototype of the optimized planar spiral coil, detailed performance metrics from simulations and physical tests, insights into the design and optimization process, and recommendations for future research. The practical testing phase will validate the simulated data, providing a comprehensive understanding of the coil's performance in real-world conditions.
This thesis is part of the NerveRepack project (EU Chips JU project, Grant Agreement nš 101112347). The main goal of the NerveRepack project is to develop a new generation of bidirectional implantable electrodes connecting the human nervous system with external mechatronic aid devices such as exoskeletons and exoprostheses, thus helping people with arm amputations or leg paralysis regain their motor and sensory functions. The optimized planar spiral coil developed in this thesis could contribute to the NerveRepack project by serving as a reliable and efficient wireless power solution for powering the implanted device.
