Caen trams with olfactory directional aid

For the visually impaired,



We offer innovative solutions for public transport users to improve and facilitate their journeys.
The principle is simple: identify a metro or tramway line by its scent.
1 line = 1 fragrance


As the olfactory sense is the most highly developed in human beings, and particularly in visually impaired people, perfume offers a new and complementary solution to hearing aids.
This accessibility solution is suitable for all users.


Example: metro or tramway networks with 2 to 4 lines.

Prestige hotels

Sensorys is supporting the Béranger Group in setting up olfactory signatures for the Evok Group's luxury hotels.

For example, our Technical Teams worked with the designers of the Hôtel Cour des Vosges to make our diffusion systems invisible by integrating them into the furniture.


The olfactory signature is present in all the areas, offering a subliminal journey to a demanding clientele.
