Are you passionate about research? So are we! Come and join us
The Luxembourg Institute of Science and Technology (LIST) is a leading Research and Technology Organisation (RTO) that drives innovation for the economy and society in Luxembourg and beyond. With cutting-edge expertise in Natural, Built, Industrial environments, Space, AI, Security and defence technologies. LIST bridges scientific excellence and applied research to design solutions that address real-world challenges and create positive impact.
In 2024, LIST and GOODYEAR signed the second phase of their partnership, 2024-2029, building on the outcomes of their previous collaboration and entering new technological areas as well. GOODYEAR-LIST partnership 2.0 embraces Luxembourg's National priorities, such as Sustainability, Digital transformation and Circular economy, through the execution of six Strategic Research Programs: Data Science for Tires, Tire as a Sensor, End-of-Life Tire Valorization, Sustainable Materials for Non-Pneumatic Tires, Sustainable Materials for Next Generation of Pneumatic Tires, Structure-Process-Properties Relationships.

How will you contribute?
LIST is seeking to recruit a two-year postdoctoral position to work on fabrication of the piezoelectric energy harvester based on ceramics for tires. This position is part of the Strategic Research Program “Tire as a sensor” in the joint project with Goodyear SA and explores how to transform mechanical energy from tires to a useful electrical energy, which can power tire sensors. The approach used for energy harvesting is the piezoelectric effect. Materials which show piezoelectric properties transform strain variation into electrical charge. These materials can be ceramics or polymers. The material chosen in this study is commercial PZT ceramics. To efficiently use the available mechanical energy in tires and induce strain in the piezoelectric material, it is essential to develop an adapted harvester's design, the transducer. In addition, harvester's signal conditioning plays an important role. To harvest enough electrical energy, all three points: material properties, harvester design and signal conditioning, have to be addressed.
This Postdoc position is mainly focused on development of energy harvester based on ceramics. Several challenges will be addressed to achieve targeted values of power from tires:
· Investigation of geometries for an efficient transfer of strain from the tire into the ceramic. The design optimisation will be done using finite element modelling (Comsol)
· Development/adaptation of signal conditioning electronics
· Integration of the harvester into a real tire
· Tests in the tire in operation
Other tasks:
· Conduct literature analysis
· Publish in peer-reviewed journals and conferences
· Present papers at scientific conferences
· Take part in the relevant training
