Optrodes for PhotoELectrochemICal ANalysis based on multimaterials FIBERs – PELICAN

The development of miniaturized electrodes has been the subject of intense research for many years because of unique beneficial properties arising at small scales. In this context, the PELICAN project aims at developing miniaturized sensors based on multimaterials/multifunctional fibers as optrodes for photoelectrochemical analysis. The ultimate objective is the integration of all elements of an electrochemical cell within a unique instrument (e.g., a working photoelectrode, a reference electrode, and a counter electrode) to design a standalone, “fully-integrated” photoelectrochemical sensing system. The approach proposed by the PELICAN consortium is the realization of multifunctional fibers combining several materials such as glasses, metals, and/or polymers. Novel Stack and draw and 3D printing approaches will be deployed to reach the challenge of the multimaterial and multifunctional fiber fabrication. The optrodes will be manufactured by employing a photoactive semiconductor electrode integrated on multimaterial optical fibers.
The PELICAN project will be structured around four work packages (WP)
- WP0: Coordination and communication
- WP1: Materials choices and fabrication
- WP2: Preforms and multi-material fibers fabrication
- WP3: Optrode designs, fabrication, and sensing measurements
The project brings together three partners: the V&C-ISCR (Rennes) and the ICMCB (Bordeaux) partners which have recognized skills in the elaboration of non-conventional glasses and fibers and multifunctional fibers respectively and the MaCSE-ISCR partner (Rennes), which has the required expertise in terms of deposition of oxide semiconductors and photoelectrochemistry.
