Student project: Global Regulation for Biomedical Implants

*Important for non-EU students: You'll need to be registered at a Dutch university to meet immigration requirements.

Explore the impact of global regulation on increasing the end-to-end efficiency of wireless powering to biomedical implants

What you will do

Wireless power transfer (WPT) systems are widely used in applications where physical connections are impractical, but their performance is highly sensitive to variations in transmitter to receiver (TX to RX) coupling and receiver load. These variations can degrade power delivery efficiency and stability, particularly in dynamic environments such as biomedical implants. Global regulation is commonly employed to maintain a stable output voltage under such conditions. However, rapid load transients, such as those induced by stimulation pulses, pose an additional challenge, as they require a short load transient recovery time (LTRT) to ensure uninterrupted and timely power delivery, especially under varying coupling conditions.

This student project aims to develop a robust and efficient global regulation strategy capable of achieving fast transient recovery. The work will explore global feedback encoding techniques to improve regulation accuracy and responsiveness. In addition, reliable uplink communication from the implant to the transmitter will be investigated to ensure stable and timely feedback under dynamic conditions. Finally, the project includes the design of an efficient power amplifier that supports the proposed regulation scheme, with the goal of enhancing overall system performance in terms of recovery speed, efficiency, and robustness.
