Context : Batteries are among the main enablers for the use of renewable energies in transportation application. To use the available resources in the best manner their lifetime still must be increased. This can be done using an adapted energy management system. For the development of a BMS digital twins bases on experimental results are required.
The postdoctoral position is part of the Horizon Europe project ENERGETICS. The postdoctoral position is funded for a duration of 12 months.

About the ENERGETICS project
ENERGETICS is a research project funded by Horizon Europe 2023 to 2026 including around ten partners from different European countries. It focuses on the design of a Battery Management System (BMS), that minimizes the battery ageing and thus increases the battery lifetime and saves resources. In the project one project partner focusses on the AI approaches and UBFC/FEMTO-ST focusses on a physical description of the phenomena as well as the battery testing to create a digital twin.

Scientific Objectives
The focus of the postdoctoral position is on the testing of a battery module in harsh use conditions as well as the contribution to a multi-physical model of a lithium battery, based on results are obtained from aforementioned and complementary tests generated the Ph.D. student in our laboratory:
• Review of the related state-of-the-art on battery module testing,
• Collection of existing approaches for accelerated ageing tests on PHEV batteries,
• Definition and conduction of characterization use and accelerated ageing tests,
• Contribution to the development of multi-physical model allowing to predict the battery behavior and aging in different conditions of battery life based on literature results and experimental results (digital twin),
• Cooperation in elaboration of battery management system and test on the digital twin.
The selected applicant will also be expected to:
• Publish in international journals and conferences,
• Participate in project meetings, in the writing of deliverables as well as in communication and dissemination events,
• Participate in the scientific activities of the respective laboratories and universities.

Context 

The FEMTO-ST research institute (CNRS) innovates in cutting-edge technological solutions for the manufacture of biomedicines (drugs whose active ingredient is of biological origin), calling on a multidisciplinary team with skills in robotics, automation, computing, microfluidics, microsystems and clean-room manufacturing. We’re looking for curious people with a good scientific background wanting to thrive in the world of research and innovation.

 Job description

The production of biopharmaceuticals requires the ability to move biological cells in a controlled manner. Among the various manipulation methods, non-contact manipulation methods using force fields [5] allow interaction with biological objects without direct contact. This avoids all issues of biological contamination, ensuring the sterility of the cells and the liquid environment in which they are cultivated. The goal of this position is to develop a device enabling three-dimensional trajectory control of biological cells using electric fields, employing electric fields as both the actuation and measurement method. For actuation, electric fields have already been used through the phenomenon of dielectrophoresis [4] to manipulate cells within microfluidic chips. Previous work within the AS2M department [2] has demonstrated the possibility of precisely controlling the trajectory of objects in two dimensions using dielectrophoresis with closed-loop control based on visual feedback. However, vision-based measurement has limitations in terms of field of view, data acquisition speed, and information pro- 1 cessing.We are therefore interested in replacing vision with impedance spectroscopy [3]. Preliminary work [1] has validated this principle as a measurement method. The development of a device for controlling the trajectory of biological cells using electric fields as both the actuation and measurement method represents both a technical and scientific challenge. It would enable the study of cellular interactions, improve the productivity of innovative therapeutic drugs, and enhance their accessibility.

Tasks

In the context of this position, you will be required to conduct both theoretical studies (for modeling various physical phenomena and performing simulation studies) as well as experimental studies requiring the design and development of electrical and mechanical systems, the implementation of control algorithms, and data analysis. You will also need to handle biological objects and work in a cleanroom environment. You will be part of a team of engineers, post-docs, PhD students, researchers, and faculty members with complementary expertise on which you can rely. In more detail, the tasks you will be required to perform are : 

• Study existing methods in the literature for actuation and measurement using electric fields

 • Characterize the couplings and the influence of actuation on measurement to propose a method enabling both to be performed simultaneously

 • Propose an efficient control law enabling the trajectory control of multiple objects simultaneously 

• Design an experimental setup (mechanical, electronic, and programming components) and microfluidic chips 

Skills

We’re looking for someone with a master’s degree, engineering diploma or PhD in robotics, automation, physics or microfluidics. The following skills are not mandatory but would be an asset for the candidate :

 • Knowledge of biology

 • Knowledge of electrostatics and a good understanding of Maxwell’s equations

 • Modeling and control of non-linear systems

 • Experience in microfluidics
