Project meeting in Thessaloniki

Representatives from all seven laboratories.

Our most recent project meeting has taken place in Thessaloniki, where we enjoyed the sunshine and excellent hospitality, whilst bringing each other up-to-date with progress and exchanging ideas. The team is on target to produce the proof-of-concept device next year.

Iordanis Konstatinidis also took the opportunity to invite Greek national TV to AUTH. On the show « Day with Color » of EPT3 he explained the problems that anosmic people experience, introduced the ROSE project and explained how the device will work.

There is considerable public interest in a wearable olfactory prosthesis.

Understanding Olfactory Disorders: A New Article from CNRS Journal

✨ The CNRS Journal, with Moustafa Bensafi from ROSE, has published a review of the causes and potential treatments of olfactory disorders (in French).  The article  highlights the importance of interdisciplinary collaboration in improving diagnostic and therapeutic approaches for these often overlooked disorders.

19th International Symposium on Olfaction and Taste

Thomas Hummel & Coralie Mignot (TUD) together with Moustafa Bensafi, Halina Stanley & Camille Ferdenzi (CNRS) attended the ISOT2024 conference in Reykjavik Iceland.


ISOT2024 was particularly well-attended (there were nearly 730 attendees from all over the world) with many interesting presentations. Here are the abstracts. Thomas Hummel (TUD) gave an oral presentation on « Trigeminal function and its association with olfactory perception » and ROSE presented a poster entitled « Substitution of olfaction by trigeminal stimulation in patients with loss of smell: technological proof of concept and preliminary results ».

Loss of the sense of smell is a sensory impairment which has major consequences in many areas of daily life: eating, sensory pleasure, social life and danger detection. To date the main therapies are surgery, medication or olfactory training, but a prosthesis-type technology enabling patients to sample their olfactory environment has not yet been developed. The aim of this study was to develop a proof of concept for such a device. The hypothesis tested in this work was that stimulation of the intranasal trigeminal system by a device that captures odorant molecules and transforms the chemical information into an electrical signal will enable patients to detect and discriminate odorant molecules via this substitution pathway. To test this hypothesis a device that combines an artificial nose with an electrical stimulator positioned in the nasal cavity has been developed. Two experiments involving normosmic individuals and patients with olfactory loss showed that individuals were able to detect their olfactory environment using the device. For discrimination, the results are less clear-cut, but show that a majority of patients can distinguish between two odorous molecules. Further experiments are underway to improve patients’ discrimination performance by adjusting electrical stimulation parameters such as amplitude, duration and frequency. Taken as a whole, this study should be seen as a demonstration of feasibility, with the next big step being to miniaturise the device.

European Innovation Council Tech Demo Day

The ROSE consortium, represented by Romain Dubreuil (Aryballe), participated in the Tech Demo Day on Medical technologies and medical devices on 15th May 2024.

The European Innovation Council Tech to Market venture building programme aims to support Pathfinder & Transition beneficiaries in their journey to transform their scientific results into innovations. Romain Dubreuil presented the ROSE project and our current results to innovation experts and received feedback on market potential at this event.

E-nose simulation

23rd January 2024

A detailed model of the human nose with a nasal cavity based on CT scans has been created by the team in Milan (POLIMI). It is now ready for testing the latest generation odor sensor with real fluid flows at Aryballe, Grenoble.

Workshop to evaluate non-functional prototypes

21st January 2024

Patients with olfactory loss have taken part in a workshop at Lyon. They evaluated a set of non-functional prototypes of our digital olfaction module, conceived and built by the team at POLIMI.

We learnt a lot about patients’ needs and their opinions of the different models in terms of ergonomy and esthetics. Their comments were very helpful. Feedback from patients both during and after the day was also positive; they enjoyed the conference and the opportunity for discussion. There is clearly a need both for effective treatments and for patient support & discussion groups.

First Olfactory Implant Conference

30th November 2023

Thomas Hummel (TUD) and colleagues organized the first international meeting on olfactory implants in Geneva. This was attended by many members of the ROSE consortium.

At a satellite meeting of this conference the first version of our proof-of-concept olfaction module was transferred from Aryballe (Grenoble) to the team at Dresden ready for tests with patients.
