Description Inductive Wireless Power Transfer (WPT) represents a significant advancement for biomedical applications, enabling the powering of implantable biomedical devices without the need for invasive wires. Achieving high efficiency in power transfer is essential, and optimizing the design of the transmitting and receiving electronics is crucial.
This thesis proposes the design and the development of an inductive WPT transmitter, operating in the 50–300 kHZ range and leveraging a class-D amplifier with the goal of maximising its efficiency at low-power transmission levels.
Starting from the analysis of the application-specific requirements and constraints, through SPICE simulations to design the system and evaluate the behavior and trade-offs in different operating conditions, the final goal is to develop, fabricate, and test a prototype of the WPT transmitter to be validated in laboratory (realistic) conditions.
This thesis is part of the NerveRepack project (EU Chips JU project, Grant Agreement nº 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 WPT transmitter will be part of a hand exoprosthesis continuously wirelessly powering, and communicating with, an active implantable device acquiring neural signals and stimulating the nerves.
