Microengineering of a dexterous probe for neural interventions (Masters thesis)
Description: Traditional rigid instruments, while accurate, remain restricted in their ability to navigate delicate and structurally complex soft tissues such as the brain. Steerable devices have made strides in maneuverability, yet their motion capabilities within cerebral regions remain constrained. We have recently introduced a novel ribbon-shaped soft robotic device that can autonomously penetrate and navigate soft tissues. The project involves further miniaturisation of the device using cleanroom microfabrication techniques and the integration of various sensors for measuring tissue mechanics as a means to diagnose various pathologies.

Closed-Loop Navigation of a Ribbon-Shaped Robotic Device in Brain Tissue (Master Thesis)
Description: This project focuses on developing an advanced closed-loop control system to navigate a robotically actuated ribbon-shaped device within brain tissue. The system integrates a custom path planning algorithm with real-time 3D pose estimation to enable precise, adaptive navigation. By continuously monitoring and adjusting the device’s trajectory based on real-time feedback, the closed-loop system enhances robustness and accuracy, essential for safe operation within brain tissue’s intricate structures. The code will be implemented in C++/Python using OpenCV for vision processing.

Optimization of MEMS Pressure Sensors for Endovascular Applications (Masters thesis)
Description: The integration of microfabrication techniques in medical devices has been transformative, yet the challenge of creating highly sensitive, miniaturized sensors for endovascular applications remains. The development of these sensors is pivotal in advancing the diagnosis and treatment of coronary artery disease. At our lab, we have initiated a project to optimize MEMS (Micro-Electro-Mechanical Systems) pressure sensors, focusing on their application in endovascular guidewires. The project aims to refine various aspects of sensor design to enhance sensitivity and reliability. As a part of our team, you will work closely with experts in microfabrication and biomedical engineering. Your primary responsibility will be to develop and implement strategies for optimizing sensor components. This will involve extensive work in cleanroom environments (CMi), conducting experiments to tweak and test different sensor configurations, and performing rigorous characterization to assess performance improvements.
