    Abstract: 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. A control circuit is configured to forward bias, during a time window of read-out of a disc of interest, the p-n junction of a disc of interest so as to place, via a thermo-optical effect, its resonant wavelength at a working wavelength, such that an optical signal propagating through the optical waveguide associated with the disc of interest is amplitude modulated.
