Patent number: 11828701Abstract: A detecting device configured to detect chemical or biological species in a given environment, includes a matrix-array sensor formed from opto-mechanical discs that are optically and mechanically resonant, able to bind to species of the environment, and arranged in rows and columns. The opto-mechanical discs of a given row are optically coupled to the same optical waveguide. Actuating electrodes are provided in order to ensure the mechanical resonance of the opto-mechanical discs. One p-n junction is associated with each opto-mechanical disc, the junctions of a given column being electrically connected to the same biasing electrode, so as to block the flow through the corresponding opto-mechanical disc of a parasitic electrical current.Type: GrantFiled: September 23, 2022Date of Patent: November 28, 2023Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Houssein Elmi Dawale, Franck Badets, Sébastien Hentz, Guillaume Jourdan, Marc Sansa Perna, Loïc Sibeud
