PhD Scholarship in Self‐Healing Flexible Biosensors for Microwave Dielectric Spectroscopy
Catholic University of Leuven Department of Electrical Engineering

The Division ESAT-WAVECORE is a multidisciplinary research group of the Department of Electrical Engineering (ESAT) at KU Leuven focusing on a broad range of topic areas ranging from electromagnetic theory, microwave/millimetre wave devices and circuits, to telecommunication systems. This PhD vacancy is in the team of Prof. D. Schreurs, which long-standing experience in microwave/mmwave experimental techniques for applications ranging from wireless communications to biomedical diagnostics. The PhD is set up as a Global dual-degree PhD in cooperation with Prof. Stan Skafidas, Electrical and Electronic Engineering, University of Melbourne, Australia.


Microwave microfluidic sensors are emerging as an inexpensive and portable diagnosis tool compared to the conventional and bulky optical techniques. The feasibility of microwave dielectric spectroscopy has been shown already but the reported biosensors were implemented on rigid microwave substrates, limiting the types of samples that can be measured. To enhance characterizations in bio-incubators and/or well plates, it is essential to investigate additive manufacturing techniques to achieve flexible though robust biosensors. The approach envisioned is metal printing on a flexible material with very good microwave properties, such as PDMS. As micro-cracks may occur during bending, self-healing techniques using Galinstan will be investigated. The challenge is not only to design such a robust flexible microwave sensor, but also to ensure its inertness with respect to water based biological samples. To improve the diagnosis accuracy, also a temperature sensor is to be embedded in the biosensor. This PhD research builds on the complementary expertise on microwave biosensor design and dielectric spectroscopy at KU Leuven, and the knowledge on additive manufacturing techniques at the University of Melbourne.


MSc in electronics engineering, with background in microwaveengineering and/or additive manufacturing. The applicant should meet the KU Leuven eligibility conditions to start the PhD without need for a pre-doc. 


PhD scholarship. The Global PhD program does not allow for a pre-doc.
