[Thesis]

Exploration of contact-less coupling technologies applied to wire network monitoring

Offer N°: SL-DRT-14-0538

Start date: 1 Oct 2014

Nowadays detection and localization of faults in wiring networks is done with the relectometry technology. The principle is to analyze reflections of RF signals injected into the wire via an ohmic connection to the conductor. However, for some applications, it is not possible to establish an electrical contact with the wires to be sensed. For such cases a contact-less solution will be required.

[Thesis]

Flexible piezoelectric transducers based on self-organised GaN nanowires

Offer N°: SL-DRT-14-0415

Start date: 1 Sep 2014

The aim of the PhD thesis is to design and fabricate piezoelectric transducers based on GaN nanowires obtained by directed growth and integrated into a flexible technology. The candidate will carry out studies on both the fundamental level – on the material – and the R&D level – on the effect of the mechanical deformation of the wires which will enable high performing device optimisation.
