**Description du sujet**:
**Project Goal**

Develop a wireless, battery-free, implantable analog interface using organic electrochemical transistors (OECTs) to sense neuromodulators like dopamine, serotonin, and acetylcholine. The readout will be performed _via_ **radio-frequency backscattering**, enabling mínimally invasive, real-time brain chemical monitoring in freely moving animals.

**Your Mission**

You will co-develop a new class of OECT-based battery-free implantable devices that combine:

- Wireless analog communication based on backscatter-modulation architecture.
- Co-design of front-end electronics and miniature RF antennas for chronic implantation.

You will prototype and characterize the wireless link (power + sensing), design and optimize sensor-resonator coupling, and participate in _in vitro/ex vivo_ testing.

**Supervision & Environment**
- **Denys Nikolayev** (IETR Rennes): expert in wireless bioelectronics and wave control in tissues
- **Simon Hemour** (IMS Bordeaux): expert in RF energy harvesting and sensing

Additional collaborations with **Nako Nakatsuka**’s group (Neuro-X, EPFL), **Damien Thuau** (IMS), and **Clémentine Bosch-Bouju** (Neurocampus, Bordeaux).

You will work in an interdisciplinary team spanning neuroscience, RF engineering, and organic electronics, and benefit from international exchanges and top-tier research facilities (e.g., IETR’s M2ARS platform, IMS’ Organic electronics & Nanotech platforms, and EPFL’s NeuroTech labs).

**Profile Sought**
- RF circuits / analog electronics
- Electromagnetics / antenna design
- Wireless sensing / bioelectronics
- Prior exposure to implantable devices or organic electronics is a plus but not mandatory.
